High in the mountains of northern Peru lies the La Arena open-pit mine, a combined gold and copper operation. The site sits along one of the world’s largest porphyry copper–gold belts, part of the Andean metallogenic area that has yielded many of South America’s major deposits. As of late 2024, the mine is owned by Zijin Mining.
The geology at La Arena is notably abrasive, with hard volcanic and intrusive formations that place significant stress on drilling equipment. These ground conditions make controlled blasting especially important, and the mine relies on pre-splitting to define stable walls and predictable bench geometries. Pre-splitting involves drilling a precise line of holes ahead of the main blast, creating a clean fracture plane that limits overbreak and improves overall pit stability.
Pree-splitting at La Arena is performed by Spanish company Acciona, a global infrastructure and mining contractor. Acciona uses 4” Down the Hole hammers paired with 5” bits. Because of the highly abrasive rock, tool life has been a long-standing challenge, prompting Acciona to run a series of comparative tests to identify equipment that could best withstand the conditions.
In mid-2025, Acciona invited Robit to participate in the tests. The setup included the Robit® H4 Marathon hammer with a TD40 shank, along with three different sets of drill bits. Robit’s DTH Drillmaster, Renato Castro, supervised the trial on site, ensuring proper operation, monitoring wear, and gathering performance data. The test period ran from June to July 2025.
The results were decisive. The Robit H4 Marathon hammer achieved a total service life of 4,740 drill meters, significantly outlasting the competitor, which reached 3,100 meters.
Bit performance showed the same trend. In the extremely abrasive rock, Robit’s bits averaged at 140 meters, while competitor bits averaged around 65 meters. Among the designs tested, the convex-face bit with Extreme Carbide gauge inserts delivered the best balance of durability and penetration.
Encouraged by the results, Acciona is exploring additional bit designs with Robit, including Extreme Carbide models, to further reduce cost per meter and improve productivity. The Marathon hammer has already convinced the contractor with its longer lifetime and penetration rates about 30% faster than the competing product.
For Robit, the successful trials represent a promising technical outcome – and the foundation for a potential long-term collaboration.

After decades of planning, the Vantaa light rail project in Finland has entered construction. Preparatory works began in spring 2025 in the Tikkurila railway station area, and by the end of the year, construction sites were launched elsewhere along the route as well.
Two alliances, one shared goal
The Vantaa light rail is being built using an alliance model, in which the client, engineering partners, and contractors operate as a single integrated team. In Vantaa, the project is divided into an eastern and a western alliance. On the west side, Destia acts as the construction contractor, with Ramboll and Sitowise responsible for engineering.
The western alliance section runs from the airport to Jokiniemi and includes a tram tunnel passing beneath Tikkurila railway station.
Tikkurila – a demanding transport hub
At Destia, the ground improvement works for the Vantaa light rail project are led by Project Manager Alexei Kesonen.
“One of the most challenging sections of the entire project is the Tikkurila station area, where an under-ground concrete tunnel of about 800 metres is being built. This requires extensive excavations, in which Robit’s drilling tools play a critical role,” Alexei explains. The tunnel will link rail traffic at Tikkurila with the future tram line, with the tram stop located underground.
Towards the end of the year, a pipe pile wall project is underway in Tikkurila. Some 400 piles of a Ø 610 mm drilled pile wall are being drilled 1–2 metres into the bedrock. The piling work is performed with Robit casing systems – Robit® DTH SR pilot and ring bits – together with an 18” Down the Hole hammer.
In addition to pipe pile walls, excavations are supported by sheet pile walls and combi walls. At its deepest point, the pipe pile wall reaches 13 metres.
“All excavation walls will later be anchored with cable anchors, drilled using a DTH hammer and Robit’s through-drilling reamers and pilots. The tunnel excavation will also include 220 mm rock sockets. 323 mm pipe piles support the tunnel base slab. All critical drilling equipment comes from Robit, and it has performed reliably,” Alexei says.
Pipe-pile-wall piling ongoing
On-site support from Robit
Robit Sales Manager Jonne Merikanto adds that, in addition to supplying tools, Robit supports the tram project by sharpening the customer’s pilot bits and servicing hammers at its Suutarila facility. Robit’s Drillmaster Raivo Forsel is also available to Destia whenever needed. “Destia has such skilled drillers, though, that they rarely need assistance,” Raivo notes with a smile.
A central location brings its own challenges
The Tikkurila construction site is located close to the railway, in the heart of the city. “This places significant constraints on the work, most notably public transport operations, traffic management, and limited working space,” Alexei explains.
“In demanding sites like this, the alliance model has proven to be an excellent solution. Its greatest strength lies in flexibility and the ability to respond quickly to changing conditions. The model allows the client, engineers, and contractors to jointly develop and adjust plans almost in real time to find the best possible solution for each situation.”
“At this early stage of excavation, the greatest challenges are likely to be underground. We expect significant volumes of pressurised groundwater and sections of poor-quality rock. The collaborative nature of the alliance model is crucial for managing and resolving these geotechnical challenges efficiently.”
Foundation works at Tikkurila station will continue well into 2026. In spring, the pile walls will be anchored at a 45° angle into the bedrock using Robit’s through-drilling Prime DT systems.
At the same time, construction of the Vantaa light rail will expand in stages to other sections of the route. If everything proceeds as planned, tram operations in Vantaa will begin in late 2029.

In 1987, some 30 kilometres north of Sodankylä in Finnish Lapland, prospectors made a promising discovery: their rock samples contained nickel and copper. It soon became clear that this Kevitsa ore find was one of the largest ever made in Finland.
In the 1990s and early 2000s, the mining rights for the deposit changed hands several times. Actual mining did not begin until 2012. Since 2016, the Kevitsa open pit has been owned by the Swedish company Boliden. In 2024, it processed almost 10 million tonnes of ore, primarily nickel and copper, as well as cobalt, platinum, palladium, and gold.
Today, Boliden Kevitsa’s polymetallic mine is one of the largest in Finland. It provides direct and indirect employment for hundreds of people in Lapland and generates significant tax revenues for the region. Production is expected to continue well into the 2030s.
Responsible metal production in Arctic conditions The strategy of the Swedish metals company Boliden revolves around responsible mining, circular-economy solutions, and the production of critical metals for the green transition. Boliden Kevitsa’s polymetallic mine is an integral part of this whole.
The bedrock at Kevitsa is demanding in all respects. The rock is both tough and extremely abrasive, says Juha Ranta, Drilling Development Coordinator at Boliden Kevitsa.
“The mixture of various ore zones, wall rock, and waste rock has formed over thousands of years. Alongside the copper and nickel, there is cobalt, platinum, palladium, and gold, and each zone behaves differently when drilled,” Juha explains.
The natural conditions in Sodankylä don’t make mining any easier either. “In winter, the groundwater in the pit is completely frozen. The hammer must operate just as reliably at -40 degrees as it does at +35 degrees in the summer. That’s a tough combination for any equipment,” Juha says.
Technologically, Kevitsa is a state-of-the-art mine. Production drilling is conducted almost entirely by remote control. From the control room, operators monitor the drill rigs working in the pit around the clock.

Testing and developing Robit’s H8 DTH hammer together
Since early 2025, Robit’s H8 DTH hammer has been tested and developed at Kevitsa in close cooperation with Boliden, says Robit Sales Director Kimmo Kangas.
“The feedback from the operators has been encouraging: the H8 is easy to drill with, penetration rate is good, and durability looks promising,” Kimmo says.
The H8 hammer has been tested with two different 229 mm drill bits to optimize the combined performance of hammer and bit for Kevitsa’s conditions.
The H8 is by no means the first hammer to be tested in Kevitsa’s demanding rock. Tools that perform well elsewhere have often revealed weaknesses in Lapland. “Here, for example, rock hardness and the way the impact energy bounces back from the rock can be very different from what you encounter in other mines,” Juha notes.
Cooperation with Robit’s product development team has been close. “Whenever we’ve found a component that doesn’t last, we’ve sat down together to decide what to do about it. Do we change the material or redesign the part completely? Recently, we’ve focused on improving the hammer’s wear life, first the ‘innards’ and now increasingly the durability of the hammer body,” Juha says.
At Kevitsa, the “Marathon” version of the H8 hammer is in use, featuring a wear-protected outer casing. The goal is to extend service life and reduce both downtime and spare part consumption.
A step towards more economical and sustainable mining
Boliden works systematically towards environmentally friendly and cost-efficient mining. “The drilling tools are one part of that. With the right tooling, you can achieve substantial cost savings, both in the equipment itself and in fuel efficiency,” Juha points out.
“Equipment durability and reliability have a direct impact on cost per drill meter. As wear resistance improves, material flows – and therefore costs – go down.”
“New surface treatment methods also allow us to make the materials more wear-resistant. Reliability improves when components that have proved weak are reshaped and redesigned.” Testing the H8 hammer at Kevitsa is part of this overall effort. “With measures like these, we keep moving towards economical mining, with green values firmly in mind,” Juha Ranta concludes.
In addition to increasing performance, the drilling industry faces ever-growing demands regarding energy efficiency and cost control. These are all issues the H Series hammer line seeks to tackle.
A modular breakthrough in hammer design
The H Series represents a novel approach to hammer design. Primarily designed for drill and blast operations and water well drilling, the hammer range is available in four sizes: 4, 5, 6, and 8 inches.
To meet the diverse demands of different drilling environments, the hammer’s modular design enables up to twelve configurations of a single base assembly for each hammer size. A lighter hammer weight combined with heavier pistons results in higher penetration rates while consuming less energy. The inner cylinders come in two displacements designed to either maximize the power output or enhance efficiency with reduced airflow demand. In addition, by swapping out only two parts, the hammers can be changed from a conventional model using bits with foot valves to tubeless versions and vice versa.
Field-proven performance
The H Series hammer line has been in development for several years, with end-user customers conducting validation trial drillings over several months in real-world settings worldwide, including South Africa. The drill and blast company Brauteseth Blasting, operating the Phalaborwa open-pit phosphate mine in the Limpopo province, has been testing the 6″ H Series hammer there. Brauteseth’s Plant Manager, Owen Du Plooy, reports an increase in the penetration rate, resulting in a 5% lower cost per meter. Other benefits he mentions include easy maintenance, good sleeve life, and a reasonable price. New technologies also bring new challenges, but Du Plooy gives credit to the technical support Robit has been able to provide at short notice.
Another Robit customer, the Drilling and Blasting Division of Zizwe Opencast Mining, serves as the drill and blast operator at the Lwala open-pit chrome mine in the Limpopo province, which is owned by Samancor Chrome. Zizwe started testing the 6″ H Series hammer in October 2024. The mixed ground conditions include fractured rock, sandstone, and clay. In line with Brauteseth’s results, Zizwe has also observed better penetration rates and quicker maintenance on the hammer, as confirmed by Operational Manager Derik Van Deventer.
Next step: the H Marathon Series
Robit has recently introduced a new version of the H Series hammer: the H Marathon Series. Engineered for extended wear life and improved durability, the Marathon focuses on reinforcing the hammer’s most wear-prone parts, such as the drive chuck and wear sleeve.
Brauteseth Blasting has also tested the Marathon hammer at the Phalaborwa phosphate mine. The trials confirmed a significantly longer service life for key components, with only one chuck needed across the entire lifespan of the hammer. The even wear distribution helped reduce downtime and replacement costs, adding another proof point to the H Series’ performance claims.
“A simple fact affects all manufacturers of drilling consumables: no two drilling sites are the same. Consequently, they need to provide the market with a vast range of tools to meet varying needs. As far as Down the Hole hammers go, Robit is looking to change this with the modular H Series hammers.”
Far North Queensland (FNQ) is one of the fastest-growing regions in Australia. Despite being the region with the most annual rainfall in the country, FNQ is facing water supply challenges. Particularly along the coast, the area’s capacity to store water for urban use is limited, which may hinder future growth. Some parts of FNQ have even seen water outages in recent years. As a result, water well drilling has proven to be a vital service for households, industries, and farms in many parts of FNQ.
One of the leading companies providing water well drilling services, as well as bore drilling and utility drilling, in the region is FNQ Drilling, a family-owned business headquartered in Bamboo. Their water well drilling service includes site evaluation, well construction, and pump installation.
In a competitive industry such as well drilling, companies must find ways to improve efficiency or reduce costs to maintain a competitive edge. Shane Naude, the owner of FNQ Drilling, switched to Robit drilling tools a few years ago.
“I was using a hammer that kept breaking barrels and shanking bits without resolution. So I asked around other water well drillers and was told to try Robit. I started using Robit in early 2023 with a D45 DHD340 hammer, a D65W HD QL60 hammer, and bits to suit,” Shane reminisces.
In September 2024, Shane got an opportunity to test and validate the performance and reliability of Robit’s new 6″ H Series hammer in water well drilling. The H Series hammer line was more widely introduced to the Australian market at the DRILL24 trade fair in Perth the following month.
A key selling point of the H Series is its modular design, allowing it to adapt to varying practical needs in the field.
“I do water well drilling in and around all FNQ for domestic, rural, and commercial clients. Ground conditions vary greatly, including shale, basalt, granite, marble, clay, and schist. So, a lot of variation in the hammer performance is needed to suit the ground,” Shane explains.
Shane’s business depends heavily on the quality of his tools. “A reliable hammer is key to my success. More drilling and less downtime due to the product not performing to specifications cost my business money and clients. Due to the remote locations I have clients at, such as stations, I require reliable and suitable products to complete my work.”
“Before switching to Robit, I had many issues with failures, e.g., a simple hammer spring continually failing and causing downtime, costing my Company money and time, and a potential loss of reputation to my business,” Shane says.
After months of validation trials, Shane’s experiences with the new Robit H Series hammer are overwhelmingly positive.
“The trial hammer has drilled approximately 500m of water bore drilling only. All components, including the hammer barrel, piston, top sub, and threads, wear better than those of competitor products previously used.”
“I’m achieving more drilled metres per day. The penetration of the hammer is powerful and punchy, which decreases the time needed to drill a hole. I have also noticed a reduction in my fuel consumption,” Shane says.
In product development, Robit has consistently relied heavily on direct customer experiences and collaboration. The H Series hammer is no exception. Throughout the trials, Shane has discussed with Robit and provided valuable feedback to further improve the hammer’s performance, always with an eye toward that competitive edge.
Phalaborwa is a vast mining complex located next to the mighty Kruger National Park in the northeast corner of South Africa. It is host to several valuable minerals such as copper, phosphate, zirconium, iron, and vermiculite.
One of the entities within the Phalaborwa complex is the Foskor open-pit phosphate rock mine. Phosphate is a critical mineral in fertilizers. Before the foundation of the Foskor mine in the 1950s, South African agriculture depended on imported phosphate rock. Today, largely thanks to Foskor’s success, South Africa exports phosphate fertilizers worldwide.
Drilling and blasting at the Foskor mine in Phalaborwa is operated by Brauteseth Blasting, a family business founded in 1983 in the KwaZulu-Natal (KZN) province of South Africa. The company started as a small-scale civil blasting company catering to KZN’s construction industry. In forty years, it has grown into a major national player, contracting to more than 20 quarries, five large-scale mining operations, and several construction sites.
Brauteseth has built its success on two cornerstones: a highly skilled, motivated staff and continuous investment in top-of-the-range technology and equipment. This focus on quality tools extends to consumable parts as well.
Brauteseth Blasting operates eight drill rigs at the Foskor mine. As their consignment agreement with their then-supplier of DTH hammers and drill bits was ending in late 2023, Robit SA approached Brauteseth, requesting a performance test of Robit’s and the then-current supplier’s DTH tools.
The extensive testing period started in October 2023 and was completed in February 2024. Robit’s tools included the D65 QL60 3½” API REG blast-hole hammer and 165 mm QL60 Flat Face blast-hole bits.
“The test results were clear: Robit’s tools outperformed the competition in terms of penetration rate and cost-per-meter”, says Duane Kukard, Area Sales Manager at Robit SA.
Convinced by the tests, Brauteseth Blasting signed a consignment agreement to supply their drill rigs at the Foskor mine with Robit’s DTH 6″ equipment.
Since May 2024, all eight of Brauteseth’s rigs in Phalaborwa have been drilling blast holes with Robit’s tools – now with increased efficiency and profitability.
Last year saw a massive geotechnical operation at the Oregon State Capitol: the entire building had to be jacked up off the ground. Robit’s micropile casing systems played an important part in the process.
The Oregon State Capitol building has faced many misfortunes throughout its history. The first capitol burned down in 1855 – only a few months after its inauguration. The second capitol met the same fate in 1935.
However, fire is not the only force of nature that has put the state capitol in peril. Large parts of Oregon, including the capital city of Salem, sit on a tectonically active fault line called the Cascadia Subduction Zone.
In March 1993, a 5.6-magnitude earthquake – the largest in the Pacific Northwest in over a decade – cracked the cupola of the Capitol and created a massive bulge on its west end. Parts of the building remained closed for repairs for almost two years.
Over the following decades, the State of Oregon conducted several studies to determine how best to protect the historic building from further seismic events. After investigating various options, the review committee decided on seismic isolation. In other words, the foundation of the building would rest on so-called pendulum isolators and a seismic joint that allows the entire complex to move independently in any direction from the surrounding ground during an earthquake.
This would be no small task; it meant that the Capitol building would have to be lifted off the ground. This would be achieved by constructing a shoring tower structure on which the building would rest while the new isolation system was being built. As the Capitol had needed extra space for years, it was also decided that an additional basement level would be constructed.
The main contractorship for the geotechnical work was awarded to Pacific Foundation, a family business based in Vancouver, WA. The company started as a smallscale drilling operation in 2012; since then, it has grown into a large contractor capable of tackling complex geotechnical challenges.
Regarding challenges, the Oregon State Capitol project was far from a typical scenario where, slightly simplified, you arrive at the job site, drill the piles into the ground – and that’s it. Here, the first challenge was to gain access underneath the Capitol and excavate enough space for the drill rigs to fit in. This phase started in late 2022.
The work continued throughout 2023 and entailed drilling micropiles into the ground across the entire footprint of the building. At best, seven drill rigs worked simultaneously in narrow spaces with only a few inches of clearance above. Two-thirds of the micropiles were Robit casing systems, while one-third, the outside piles, were double rotary systems. The micropiles supported a total of 175 shoring towers upon which the jacked-up building would sit until the work was completed. The tower construction and the jacking operation were performed by trusted partners.
By Christmas 2023, the micropiles, totaling as many as 722, were installed. By late January 2024, the building was resting on the shoring tower structure, paving the way for the seismic isolation system and reconstruction efforts.
For Pacific Foundation, mission success has probably never been more critical. The project required massive amounts of structural engineering and careful planning and coordination by all participating parties to stay on schedule and maintain safety – not to mention that while the work was in progress, the state legislature was in session just a few feet above.
The construction work at the Capitol will continue into 2025. Once finished, the historic marble building should finally be able to stand firm against any future seismic events.

Kauno Määttä was a familiar name to Finnish wrestling fans in the 1960s and 70s: he won the Finnish Greco-Roman wrestling championship in his weight class several times. In his day job, however, Kauno did not make the headlines despite being a respected professional: he drilled wells.
Kauno’s career as a driller continued into retirement and was passed on to the next generations. In the late 1980s, Kauno’s primary school-age grandsons, Sami and Simo Manninen, got the spark when they got invited as helpers for a well-drilling job.
The spark ignited a lasting passion, and as a result, the brothers’ own company, Oulun Porakaivot, was finally born in 2012. It operates throughout Finland, and its core business is drilling geothermal energy fields for large properties. Oulun Porakaivot also handles the design and permitting of the energy fields and has a wide range of customers from the public sector to commercial properties and housing cooperatives. They also drill individual geothermal and water wells for detached houses and other small properties.
Oulun Porakaivot operates six drilling rigs and has long been Robit’s contract customer, using Robit products for all key consumables such as rods, ring bits, drill bits, and pilots. Panu Haulos, Design Engineer at Oulun Porakaivot, has noticed a welcome improvement in the quality of drilling tools.
“Reliability of consumables is critical in this sector. The wells are getting deeper – up to 450 meters – and the plots of land are often small: if the first hole falls short, there may not be enough room to drill a new one. In consumables, we have to look at the cost of a drill meter from an overall economic perspective: performance, drilling speed and fuel consumption. Robit’s products have been consistently reliable and have performed excellently in deep wells. And today’s hammers and bits are more durable than before,” says Panu.
For about a year, Robit has been developing a new four-inch DTH hammer, branded Robit H4, for well drilling. Testing in cooperation with customers is an integral part of product development. The H4 hammer was optimized and finalized as per customer feedback. Robit’s Sales Director Kimmo Kangas approached Oulun Porakaivot and offered them an opportunity to test the new hammer. A suitable test site was found in Helsinki, at a housing cooperative’s future energy field, where 23 wells will be drilled to a depth of 390 metres. Kimmo has followed the development of the H4 hammer from the beginning and has seen its potential.
“The functionality, reliability and penetration rate of the H4 are outstanding. However, the most significant improvement is fuel consumption, which is significantly lower than the competition. Typically, for example, in a 200-meter well, the compressor consumes about two litres of fuel per meter. On the H4 hammer, the consumption has been as low as one and a half litres. That’s a crucial difference,” says Kimmo.
Low fuel consumption is one of the key assets of the H4 hammer.
Panu Haulos confirms that the H4 has achieved very low fuel consumption figures at the drilling test site. The two companies have been in close cooperation for years.
“Robit’s domestic production is definitely a plus for us: we can get parts with a fast response time. They react quickly to our needs, around the clock if necessary. Robit has also been able to help in special cases where off-the-shelf products have not been available. For example, we had a project where the hole we were to drill had to be absolutely straight. Robit tailor-made us a special guiding rod that did the job,” says Panu.
In many sectors of the economy, growth indicators have recently taken a downward turn. This is not the case in the thermal well market, at least not for Oulun Porakaivot.
“The trend is upward, and demand is constantly growing and diversifying. Of course, this is partly due to technological advances that allow us to drill deeper wells. In Finland, the city of Helsinki, in particular, is a strong driver of progress in this field. The city, striving to move away from fossil-based district heating, has streamlined the permitting process for geothermal heat”, Panu says.

Thanks to its rich gold deposits, the Cajamarca region in northern Perú has been home to gold mines since the Inca times. One of the current mines is Cerro Corona, where Robit recently became the preferred supplier of DTH drill bits.
Cerro Corona mine, owned by Gold Fields Inc, is located on the eastern slope of the western Andes, some 80 km north of the regional capital of Cajamarca. The open pit mine is expected to produce some 2.1 Moz (about 60,000 kg) of gold and 407 kt of copper in concentrate over its 15-year mine life.
The rich gold deposit is hosted by diorite porphyry, an extremely hard rock embedded in limestone. MUR-WY, the drilling contractor at Cerro Corona, uses the so-called pre-splitting method, where closely spaced holes are drilled and lightly charged, causing fractures that isolate the gold-bearing rock from the surrounding rock mass. Successful pre-splitting requires very straight holes, and, as always, this should be achieved with optimal cost, penetration rate, and tool lifetime performance.
Robit believed their tools might improve productivity, so they contacted MUR-WY in 2021 to arrange test drillings for 5” DTH bits at Cerro Corona. Test drilling is typically a very hands-on type of work where you monitor and make adjustments on the spot with the contractor. However, the COVID pandemic complicated things.
“In 2021, access to the mine was heavily restricted, so we had to get creative with MUR-WY to follow up on the tests. We ended up monitoring the performance remotely through WhatsApp videos and messages”, says José Luis Cisneros, General Manager of Robit SAC.
Luckily the restrictions were eventually lifted, and Robit’s Regional Sales Manager, Martín Rodriguez, was able to revisit Cerro Corona and conclude the tests, which proved highly successful.
“On average, compared to the tools they had used, we reached 20 to 25% better yields with our DHD340 Flat Face Premium bits and 40 to 50% better with our D45 HD hammers.
“We detected several ways to improve productivity. Not only did Robit’s components perform better, but a key factor is also the service we can provide. We are now the preferred supplier for DTH consumables at Cerro Corona. There are still challenges to tackle, but we will work with our strategic partners from MRU-WY to articulate better ways to approach their needs and increase security regarding the project’s required logistics”, Martín says.
In the first half of the 20th century, the Norra Djurgårdsstaden district in Stockholm, Sweden, was a busy industrial center and port area with an oil port, a coal port, a free port, and even a seaplane base. Today, it is one of the largest urban development areas in Europe.
The Norra Djurgårdsstaden development project was kicked off in the early 2010s. The first 700 apartments were completed in 2012, and construction work is expected to continue well into the 2030s.
The overall plan includes construction work in five sub-areas in the district. One of them is Project Saltkajen in Södra Värtahamnen, where a new pier with an associated bridge will be constructed, and the existing quay will be rebuilt. The city of Stockholm signed the contract, worth SEK 610 million, with Skanska.
Foundation work for the project includes extensive pipe piling and sheet piling in demanding conditions: more than 500 SSAB RD pipe piles (711 mm and 508 mm) will be drilled and connected by welded interlocking sections, creating a continuous retaining wall against horizontal and vertical loads.
Skanska chose the Robit Steel Fist (SF) casing system to drill the RD piles. SF is a solid choice for all DTH applications where the casing is left in the ground. Skanska has successfully used it in previous projects, such as the Slussen reconstruction in Stockholm.
As construction continues, Norra Djurgårdsstaden is slowly transforming into a modern, environmentally friendly, sustainably built district with 12,000 homes and an estimated 35,000 new jobs. Värtahamnen will be home to some 5,000 people, and 20,000 will work there. With new walkways, shops, restaurants and nightlife, it will also be an inviting entry point for international visitors arriving in Stockholm by boat.
When developing products for use under several conditions, it is vital to consider the experiences of people using the products. In modern times, it is possible to simulate all sorts of conditions in a lab environment or using computer models. But these can often only give an indication of the product’s performance in the real world, whereas those working in the conditions set by said real world can tell you a lot more.
For the above reasons, Robit has a long tradition of working with its distributor partners and end-customers alike regarding product development. The end-users know their equipment and circumstances better than anyone, so they can often test new and existing products under true-to-life conditions. This way, one can ensure that the test results correspond to the products’ actual performance and durability capabilities.
Collaborating towards better efficiency
One of Robit’s long-term test partners is Stevin Rock, which operates a limestone quarry in the United Arab Emirates with a fleet of Down the Hole (DTH) machinery. They have been using Robit-manufactured DTH tools since 2016. Stevin Rock has been using the full suite of Robit’s drilling consumables, with a 4″ hammer as their workhorse of choice and adaptors, drill tubes, and 110 mm and 127 mm bits aiding the work.
The initial contract was made after Robit succeeded in the trials at the Stevin Rock quarry. Robit’s products triumphed with a longer life span and lower cost per meter than the competition at the time. While some alternatives provided a higher penetration rate, this benefit was trumped by the higher number of breakages it brought. They decided to go with Robit, which offered known products that provided conclusive and consistent high performance.
In the years since the initial contract, Robit has proven itself as the right choice with an excellent overall life span of products, a high level of service, and numerous supporting drill master visits. Indeed, these visits have been the core of the support and collaboration towards the customer. A Robit drill master has been visiting the site on support duties a couple of times a year to help Stevin Rock optimize their processes. In addition, Robit and their distributor partner DeltaCorp Global have conducted on-site practical and theoretical training sessions for the operators and mechanic teams on hammer assembly, preventative maintenance, bit wear, failure modes, and best drilling practices.
Robit always aims to find the best possible distributors for each region; the goal is to find those who understand the local market, culture, and general thinking. In DeltaCorp Global, Robit has one such winner. During the years, DeltaCorp has fostered a very close working relationship with Stevin Rock. This allows them to consistently offer timely and relevant support for the customer across their organization. DeltaCorp’s representatives conduct at least one visit each week to one of Stevin Rock’s three sites. The purpose of the visits ranges from stock deliveries to management meetings, where product quality and life span, as well as stock levels and forecasts, are assessed. While on-site, the representatives will also visit the drill rigs to receive direct feedback from the drill operators. On top of all that, the DeltaCorp representatives maintain constant communication with Stevin Rock’s site management, working swiftly in the event any concerns should be raised, such as a sudden need for urgent deliveries, an unforeseen breakage, or some other operational problem.
Thanks to continuous support, Stevin Rock has improved the results they get with their equipment even further. When the initial contract started in 2016, the average life span of a drill bit was 2,000 meters, with hammers reaching approximately 8,000 meters. With all the training given to the personnel to help them make the most out of their tools, the efforts to optimize the drilling processes, as well as the product improvements from Robit’s Engineering and Production teams that based on the customer’s feedback, the average bit life span has extended to 4,500 meters, with the hammers regularly exceeding 25,000 meters.
While the durability and solid performance of the drilling consumables first made Stevin Rock give Robit’s drilling tools a chance, they have since gotten several more reasons to stick to their decision. And while they have been periodically testing multiple competing products, they have not had a reason to switch.
“We have been using Robit’s products for years and cannot fault their performance or service. We run an open tender every two years, and they always come out on top. Robit’s commitment to collaboration and continuous improvement is their great strength. However, their local Distribution Partner is also strong; with their reliable supply chain management and quick reaction times, a solution is always available to us 24/7.”

Collaboration as the basis for product development
During their years working with Stevin Rock, Robit has been conducting numerous tests on many hammers and bits. All these tests have aimed to increase the life span of the products, as well as their performance, with minimal downtime and breakages so that the customer can reduce their drilling costs to the minimum. Tests carried out with customers have been at the heart of Robit’s product development process. Those trials have led to discoveries and breakthroughs that have guided the designs of their latest products, with the upcoming H-series hammers as a good reference point.
The new H-series hammers have been designed with performance and versatility as their guiding principles. The goal was to provide customers with a hammer range that they could utilize in different environments with minimal breakages and maximized utility for each operator’s circumstances. Customer feedback led Robit to develop a new modular design, offering increased flexibility and adaptability to varying conditions. With a few simple changes in the assembly of the hammer, the user can customize it for their needs; whether one wants to run them with improved productivity in mind or needs to be able to use a lower capacity compressor, the H-series hammers can be modeled to suit these requirements.
In practice, the modular design allows Robit to offer four hammers in one base design. The assemblies vary between high power and low volume, as well as foot valved and tubeless. Thus the following variations are available: high power with a foot valve, high power tubeless, low volume with a foot valve, and low volume tubeless. The high-power assembly offers high blow energy and air volume, resulting in a fast penetration rate and is suitable for deep-hole drilling. On the other hand, the low-volume assembly provides lower blow energy and air consumption, which are ideal for soft ground while keeping the hammer energy efficient.
As an example, Stevin Rock was looking for a faster drilling hammer to improve the potential productivity. Robit provided them with two assemblies of the new H-series models with differing internal arrangements to control the airflow, one with low air volume and the other with high air volume. These new hammers were to be tested against the tried-and-true D45 hammer from Robit’s older hammer range. The tests showed a considerable, consistent improvement across the board. The penetration rates went up in all tests, with the smallest increase at 14% and the most significant improvement at 30%. The highest penetration rate reached during the tests was 63.18 meters per hour. These results also correlated with those seen in earlier trials, ensuring the validity of the results.
With the new hammer range, Robit wants to bring more options to the market while still guaranteeing high performance. Because if one thing has become crystal clear during their collaboration with their customers, no two drill sites are the same. For this reason, they will make sure to let their customers’ and distribution partners’ voices be heard when developing new products and improving on the old ones.
This is an edited version of an article originally published in Global Mining Review, May 2023.
Peñasquito Mine, located in the State of Zacatecas in Central Mexico, is the second-largest silver mine in the world and also a major producer of gold, lead, and zinc. The giant has been successfully served by a fresh partnership between a new dynamic distributor and Robit.
The scale of operation at Peñasquito is so massive that it’s more like a small city than just an open-pit mine, with its own airport, a 1,900-bed camp with full dining, laundry and recreational facilities, and even a radio station. Opened in 2010, it currently produces some 31 million ounces, or almost 900 tons, of silver per year.
Mining is a thriving industry in Mexico, with several distributors competing over their share of the drilling consumable market. Peñasquito Mine is owned by Newmont, the world’s largest gold mining corporation. This did not stop Marlous Supplies and Services, a newcomer in the field, from landing a distribution deal for Robit DTH tools with Newmont.
Marlous was founded in the spring of 2020 by Martín Ocaño, who has an accomplished track record in the business.
“I have dedicated 24 years to the commercialization of products and services, in mining and public and private companies. For years I had been working on the idea of forming a company dedicated to supplying different products to the mining industry”, Martín says.
“Our key strength against the competition is that we focus completely on giving good attention and service to our clients, always covering their needs, interests and concerns, including after-sales. This has distinguished us and helped us enter and gain ground in the toughly competed mining market.”
In the search for a reliable supplier for drilling tools in their portfolio, Marlous decided the best option was Robit, given their experience and product quality. In the case of Newmont Peñasquito, Marlous was in the right place at the right time.
“Newmont’s main supplier of drilling tools was failing to deliver products in time. We had a similar product available, so we were able to help them out, and from then on we were allowed to start serious testing”, Martín recalls.
Currently, Marlous is supplying a major part of the DTH drilling tools used at Peñasquito. These include Robit D88 and WH4 hammers as well as QL80 and TD40 drill bits.
A key factor in their success at Peñasquito has been the technical personnel working on-site in close cooperation with the Newmont staff. This includes monthly meetings where the results of the previous month are analyzed and points of improvement can be identified.
“We are always open to feedback and encourage our customers to comment on any detail, anomaly or possible improvement. They appreciate it when their comments and observations are taken into account and implemented as soon as possible”, says Martín.
Still a young and small company, Marlous has already established a firm foothold in the Mexican mining sector. Growing steadily, the company is building on a balanced synergy between the quality of products and impeccable customer service.

Rich in copper, silver, gold, and lead reserves, Peru is a global giant in the mining industry. Iron ore is also a significant export, although known deposits are limited to a single region.
Antonio Raimondi was an exceptionally versatile scientist. Born in Milan, Italy in 1826, he emigrated to Peru in 1850. A year later he became a professor of natural history at the National University of San Marcos in Lima. In the following years, he founded a medical school and a chemistry department there. Raimondi was also a passionate geographer, traveling extensively across the country conducting geological, botanical, and zoological studies. It was on one of these journeys that he discovered a vast iron ore deposit in the Marcona District in the Nazca province, some 500 km south of Lima, in 1870.
It wasn’t until the 1950s that the exploitation of iron ore in Marcona began. Since 1992 the open pit operation has been run by the Chinese-owned company Shougang Hierro Perú, during which time the production of iron has grown sixfold.
A large share of the drilling and earthmoving operations at Shougang Hierro Perú is conducted by Cosapi Mineria, a subsidiary of Cosapi S.A., one of Peru’s biggest construction and engineering companies. Cosapi Mineria specializes in massive earthworks and the development of open pit mines.
An open pit operation typically makes extensive use of Down-the-Hole tools for pre-split and buffer drilling. That’s why Shougang Hierro Perú was an attractive target for Robit SAC to approach with their offering.
“The iron deposit at Shougang Hierro Perú consists of very hard and abrasive materials. You can find competent soils with compressive strengths of 250 to 300 MPa”, says José Luis Cisneros, General Manager of Robit SAC.
“We contacted Cosapi Mineria and carried out the first test in early 2020 with 7-inch bits and a D65 hammer. Since then, we have been working ever more closely with Cosapi, providing them with material innovations to increase performance.”
“In recent months we have been working together with Cosapi in a testing process of the main DTH providers in the market. Thanks to the constant monitoring by our Assistance Engineer Kevin Salas, and the development of the right products through our DTH Sales Manager, Martín Rodríguez, we have been able to generate new ways of improving the operation and proposing drilling targets with higher standards”, José says.
The open pit operation requires a lot of double bench pre-splitting, performed with D45 HD hammers and 5-inch bits, ballistic buttons, and a convex face. The bits have obtained an average duration of 1,400 meters, and an average speed of 32 m/h.
Recently, Cosapi signed an extension contract for their operations in two of the open pits at Shougang Hierro Perú. Impressed by the tests conducted with Robit, they granted a consignment agreement, trusting Robit with 60% of the consumption of drilling tools over the competition.
“This is the first contract of consumption for DTH tools in Latin America where we will provide assistance and stock for the client’s operation, including technical service, maintenance of hammers and management of drill bits”, says José.
“We hope to show Cosapi Mineria and the market that Robit SAC has the necessary resources to keep exceeding the expectations of our strategic partners.”
Carbon neutrality is a globally accepted goal to minimise the negative effects of climate change, in which energy production plays a key role. The current military crisis in Europe is a reminder that nations should also strive for maximal energy self-sufficiency. Geothermal energy provides one promising, cost-effective path toward achieving both goals.
In Finland, the growth of geo-energy has been rapid in recent years. One of the key actors in the sector is Rototec, Europe’s largest geo-energy company with more than 60,000 energy wells drilled. Founded in 2007, Rototec has grown strongly in Finland and operates also in Sweden and Norway.
While geothermal energy has long been a popular energy source for single-family houses, Rototec is focusing more on supplying geo-energy for large properties such as hospitals, shopping centres, and factories.
A geothermal system requires one or more bore wells, drilled to a depth of 150–250 metres, depending on the amount of energy required. Robit has been supplying Rototec with drilling tools since the early years of the company.
“Robit, as a big domestic manufacturer, was a natural choice for us. 99% of the holes we drill are four-inch wells and Robit has a comprehensive line of tools for that. Currently, all our drill bits are from Robit,” says Hannu Puolitaival, Technical Director at Rototec.
The fruitful, mutually beneficial cooperation spans back more than a decade and focuses on customer-oriented service.
“Over the years, we have worked closely together to develop drill bits to better meet our needs. We test the products, and share our experience and comments with Robit for further development. One of Robit’s assets is their agility: after our feedback, they can produce new, improved prototypes at a fast pace for testing. Of course, the fact that they have domestic manufacturing helps too,” Hannu says.
“Another strength is that Robit can make small batches. If we’d need, say, five units of a particular new drill bit for testing, that poses no problem. Not all manufacturers can do this,” says Hannu, and adds one more thing: “I have especially liked the fact that Robit has a dedicated person managing all communication with us. It makes our cooperation seamless and straightforward.”
Wolfe Island sits at the north-eastern end of Lake Ontario, at the entrance to the Saint Lawrence River. The Canada–US border runs immediately to the south of the island, leaving it on the Canadian side. A ferry connects the island to the city of Kingston, Ontario.
A popular destination for nature lovers, Wolfe Island’s resident population tends to double or triple in the summer. For years, the ferry has been running near or even over capacity during the busy seasons. That’s why the Ontario Ministry of Transportation launched a major improvement project in 2020. Its goal is to replace the old ferry with a new, larger one, which requires significant upgrades at both ends of the ferry line: Kingston Dock on the mainland and Marysville Dock on Wolfe Island.
The General Contractor for the Marysville Dock project is Facca Inc. from Lakeshore, Ontario. A family business now in the fourth generation, Facca has built a reputation as one of the premier civil construction contractors in Ontario over several decades. They perform all the foundation work, and most of all other work on the Marysville Dock project with their own forces.
“We have been doing our own deep foundation work – piled foundations and sheet piling, some drilled shafts in earth – for about 15 years now. However, this job is only the second for which we’ve performed hard rock drilling of this scope, and the first we’ve done completely with our own forces”, says P.Eng. Steven Gardonio of Facca.
On their Down the Hole hammers for the project, Facca has used both the Robit DTH Prime system and the Robit Steel Fist system, supplied by Pinnacle, Robit´s Canadian distributor. Through their extensive piling expertise, Pinnacle’s Mitch Yorston and Jim McPhail have also provided valuable technical support for Facca.
“We’re putting in about 1,800 m of caisson with the Primes through a mixture of clay, sand, and till, with 250-ish meters of that socketed into the very strong (approaching 200 MPa UCS) limestone bedrock.” “There are a total of 87 caissons on the contract, some more than 27 meters in length. Nine were first installed on a dolphin from our barge with technical assistance from Pinnacle. This work went so well that we decided to purchase from Pinnacle the drill setup required – Down the Hole hammers and associated – and the remaining caissons were installed at the main ferry dock”, Steven explains.
“With the Steel Fist, we’ve been drilling some of the more difficult of the approximately 220 toe pins embedded 2.4 m into the bedrock.”
“We’ve been extremely happy with the performance of our equipment from Pinnacle and Robit bits. All drilling is full RC, and the process of drilling overburden – soft to hard clay and dense glacial till – from inside of the pre-driven pipe piles and locking into the ring bit at depth has not been an issue at all.
“Often, we can lock into the rings without halting rotation, very smooth, as was the drill-through process. Same for the Steel Fist, we’ve managed to drill material out from piles without rotation so as to not engage the wings and lock into the shoulder at depth, saving us significant time. We realize this is unorthodox, but it’s been working for us”, Steven says.
The CA$70M ferry dock project is still very much in progress. If everything goes as anticipated, Wolfe Islander IV, the new state-of-the-art, fully electric, zero-emission ferry – first of its kind in Canada – will start operating between the new Kingston and Wolfe Island docks in November 2023.
As far as mineral reserves go, Kazakhstan is in the top twenty in the world, and mining comprises almost one-third of the country’s export earnings. No wonder then that the competition in the sales of all mining-related goods, including drilling tools, is very tough. Robit secured a distribution deal with a key player in the region.
As a major global exporter of minerals, Kazakhstan benefits from its central geographical location between Europe and Asia. This is also reflected in the name of the largest company supplying machinery and equipment for mining and construction in the area: Eurasian Machinery LLP.
With more than 600 employees, Eurasian Machinery provides customers with high-quality technical services through ten centers in Kazakhstan and Kyrgyzstan. Besides being the official distributor of Hitachi Construction Machinery – their spearhead product line – they also supply the industry with machinery and equipment from a host of other high prestige global brands. As of August 2021, these include Robit.
George Apostolopoulos, Robit’s VP, Global Sales, is thoroughly familiar with the Central Asian market and sees great synergies for Robit in the exclusive distributor agreement with Eurasian Machinery.
“Eurasian Machinery have a strong reputation in the Kazakh market. They have done an excellent job with the Hitachi Construction Machinery brand and have placed themselves among the preferred suppliers for the country’s mining industry. They are present with equipment and service contracts in most of the mines in Kazakhstan and Kyrgyzstan”, George says.
“Customer satisfaction is driving their efforts and they are providing high-quality services to the industry. A high-tech Component Repair Center in Karaganda serves the purpose very well.”
“This is a very significant deal for Robit as the Kazakh mining market is among the biggest in the world. It’s the 2nd largest within our East sales area after Russia. It could provide significant leverage for our sales; big opportunities exist for our Top Hammer products both underground and surface, as well as our Down the Hole offering.”
“There is some tough competition in this market not only from the traditional players but also from low-cost suppliers. This makes it particularly important for us to have a renowned and well-represented distributor in this market”, George concludes.

In the late 19th century, Helsinki was growing and industrialising rapidly. This was particularly evident in the seaside district of Sörnäinen, which became the largest industrial area in the city after the construction of a cargo port and a railroad track. Now the port and factories are history, but the neighbourhood – now called Kalasatama or “Fish Port” – will remain an integral part of the Helsinki maritime cityscape in the future. That future is now being built in Verkkosaari, at the northern end of Kalasatama.
While the southern Kalasatama has been under reconstruction for years, Verkkosaari was sitting idly for a long time. Its 13 hectares are now zoned for a residential area for 3,600 people, a large daycare centre, and a marina. To start with, more than 200,000 tonnes of contaminated soil had to be removed. Before construction work can begin, the soil needs to be reinforced. New land is also being built on top of the sea, where some of the buildings will arise.
At this moment, work at Verkkosaari is in full swing with excavations, earthfilling, pile drilling, and other groundwork. Drilling contractor Fingeo is drilling micropiles for road base support, in cooperation with the main contractor GRK Infra. The jobsite is demanding.
”Most of the challenges are caused by the old structures, concrete piles, wooden piles and other materials buried in the soil. It’s former seabed that had been gradually filled since the early 1900s”, says Tuomas Perkiö, supervisor for Fingeo.
The jobsite is also exceptional in scope. “This is the largest micropiling project ever in Finland. We have a drilling contract for 6,000 piles, 110 km altogether”, Tuomas recounts.
Fingeo started the pile drilling work at the beginning of 2020 with one drill rig. By November they were operating five drill units and had laid down some 3,800 piles, which equals to 63 kilometres. The remaining 2,200 piles will be drilled by autumn 2021.
Fingeo uses Robit’s pilot bits and reamers in the drilling work, which has progressed without a hitch. ”Robit’s pilots and reamers are doing a great job. At best, we have drilled more than 8 kilometers with a single bit. Cooperation with our Robit contact Sami Paavola has also been excellent: deliveries run smoothly, and Robit reacts quickly to our requests and provides support whenever needed”, says Tuomas Perkiö.

The remaining infrastructure works in Verkkosaari are scheduled to be completed in 2022, allowing the actual construction phase to begin. Kalasatama as a whole is one of the largest construction areas in Helsinki, and it will keep taking shape well into the 2030s.

Copper mining has been a key driver of Chile’s economy for centuries. Among the country’s mining companies, the state-owned Codelco is the crown jewel. It’s the world’s leading copper producer with immense mineral reserves, and a driving force for the entire country’s development.
Codelco’s major mining sites include El Teniente, “the Lieutenant”, the world’s largest underground copper mine which has been in operation for 200 years and currently has a capacity of 400,000 tonnes.
The second largest mine is the century-old Chuquicamata, or “Chuqui”, as the locals call it. Since its open pit operations had grown increasingly uneconomic over the last years, Codelco made a huge investment switching to underground cave mining in 2019. Chuqui’s current capacity is 377,000 tonnes. Andina, the third largest mine nested at the dizzying height of 3,700–4,200 metres on the Andes, consists of the Rio Blanco underground mine and the Sur Sur open pit.
As of late 2020, Robit will be the main supplier of Top Hammer and Down-the-Hole drilling tools for Codelco’s three largest mines. This is a result of decisive cooperation between Robit and their Chilean distributor Full Safety.
Founded in 2010, Full Safety had focused on dealing in clothes and footwear for special target groups such as armed forces, law enforcement, health professionals – and the mining industry. The last-mentioned seemed like a promising sector for new business opportunities, and in 2015 they contacted Robit.
“We were looking for new strategies, and we met Robit at the right time. After consulting with them we restructured our business model over the next few years by opening a new office and recruiting sales personnel as well as drillmasters for field support. In turn, Robit offered us training and technical-commercial support on client visits, and participated in mining fairs with us”, recounts Cesar Cornejo, General Manager of Full Safety.
Getting a foot in the door of a global giant like Codelco is not a simple thing. Despite persistent efforts, discussions on arranging a comparison test to prove the quality of Robit’s consumables led nowhere. As a change of plan, Full Safety approached Astaldi, the main contractor at El Teniente – and they agreed to a head-to-head test between Robit and their then-current brands.
The February 2020 tests, involving bits, drifter rods and couplings, did not disappoint: Robit outperformed the competition by some 30% in terms of lifetime and penetration rate. A letter of certification by Astaldi opened the door to participate in a tender for Codelco. Full Safety and José Antonio Rodríguez, Sales Manager for Robit SAC, then carefully fine-tuned an offer that proved the most competitive.
This major achievement, however, is just the tip of the iceberg. The Chilean mining sector has vast growth potential for the Robit-Full Safety partnership, and several other tenders and product tests are already underway across the country.

Stevin Rock LLC is one of the largest quarrying companies in the world, operating in the Middle East, on limestone, dolomite and gabbro minerals. Stevin Rock LLC produces over 80 million tons of the above minerals each year, drilling at the same time over 1.5 million meters.
After stringent trials with multiple competitor products over months, Robit products were found to have the least cost per meter in operations. Thus, the first contract was signed in 2017 for 2 years. After consistent performance for these 2 years and once again testing all competitor products, Robit was again found to have the most competitive performance. Robit was once again awarded the contract for the next two years covering 2019 and 2020. During these periods 2017 to 2020, Robit has been continuously improving its products based on customer feedback. As a result, Robit products have been regularly improved repeatedly.
Robit has also conducted regular drill master visits as well as conducted regular classes for Operators and Mechanics on optimum parameters for getting the best life of the product.
A combination of timely product evolution, regular training, visits of Drill Masters, 100% on time delivery and zero down time loss on account of product performance had contributed to the success of the product.
Robit is represented by Deltacorp Global FZE in the United Arab Emirates. They export to over 15 countries and operate from 2 warehouses in Duty Free Zone, in UAE.
