Button bits
All of the Robit® button bits are manufactured of new 100% recyclable steel. In the environmentally friendly steel production process the CO² emissions have been reduced 80% and 95% of the waste is recycled including the process smoke which is filtered. The new steel grade gives even more uniform properties and improved fatigue strength which is crucial in rock drilling process. Designed for particular applications from soft rock formations to extremely hard conditions.
Models:
• A, AR – medium and hard rock model
• B, BR – hard + abrasive rock model
• DS, DSR – drop center model for straighter holes
• M – soft and medium hard rock model
• S, SR – all around model

DTH-RoX NS
Non-Stop system for down the hole hammer
Robit® Non-Stop system is an advanced casing system that start to drill with a casing and then to continues beyond it without tool changes. No need to pull out the pilot bit and the drill string to replace it by a conventional down the hole bit. A single operation disconnects the pilot and the ring from the casing. The drilling can be continued free from the casing tube without losing the drilling diameter.

DTH-RoX MU
Multi-use system for down the hole hammer
In some overburden drilling applications the casing has to be removed from the ground. This sets higher requirements on the durability of the equipment. Double groove design* in the casing shoe and the best materials available guarantee that Robit® Multi-Use system does not fail even in the most difficult conditions. Robit® Multi-Use system is available for all the common DTH hammers.

DTH HZ
Horizontal system for down the hole hammer
The loads in Horizontal Drilling that the casing system must endure are severely higher than in typical vertical drilling. Robit® has developed a system which is capable of handling even the toughest conditions.
The Robit® HZ -system consists three parts; pilot bit, ring bit assembly with the ring bit and protective layer and impact shoe. The pilot bits hits directly the casing via the welded casing shoe. This causes that all the efforts of pulling the tube is diverted to the impact shoe and not on the ring. The ring bit is rotated with the pilot bit. This system leads to a longer life time of the ring bit, better penetration during drilling and increased reliability to finish the hole on time and according to plans.

Rotary drill bits
Rotary Drilling relies upon high rotational speeds and thrust without percussion to achievethe desired effect and outputs. In rotary drilling, the rock is made to fracture by means of a combination of “pull down” pressure on the bit and rotational power “torque”. Weight is applied to gouge, chip and grind the rock. Tricone rotary bits are sometimes a good alternative to a DTH hammer.
• Available in TCI (carbide buttons) and mill tooth configurations.

Drag bits
A drag bit is a drill bit usually designed for use in soft formations such as sand, clay, or some soft rock. However, they will not work well in coarse gravel or hard rock formations. Uses include drilling water wells, mining, geothermal, environmental and exploration drilling. Whenever possible, they should be used to drill pilot holes because they produce cuttings that are easiest to penetrate.
• Key design features provide industry leading penetration rates coupled with long service life
• Centre Face flushing opening providing optimal pick cleaning
• Plasma Transferred Arc (PTA) wear protection for extended block & wing service life

S-Sense
Do you know where the end is of the holes you drill? You can now, with Robit’s new measuring technology. The system is the result of an intensive, seven year R & D program at Robit and is in operation at selected customers. Unlike existing, time-consuming manual systems, measuring during the drilling process does not require an extra work phase in the drilling process. The measurements are available immediately after drilling a hole. You can see a 3 D view of the drilled hole in the drilling pattern.
When drilling holes in rock, the holes often turn away from the desired direction, and in long holes the deviation may even be several metres. Hole deviation results in inefficient operations on a site and in the worst case may create hazards. The new system measures the actual straightness of drill holes immediately, so the information can be utilised in optimizing and charging a rock face.
Optimizing charging raises efficiency in drilling by:
- Optimizing crushing aggregates through controlled charging and blasting, no oversized boulders
- Ensuring safe blasting without the risk of flying rocks
- Optimizing yield from the orebody by avoiding drilling into waste rock
- Increasing the overall productivity of the blasting and crushing process
- Cutting costs for fuel and explosives and reducing downtime
- Storing all drilling data in a database to develop your drilling process
- Raising overall efficiency
Since the results are obtained immediately, it is possible to react to any hole deviation when positioning and directing the following holes. The system functions in all types of rock formations – even in magnetic ore.

Do you know where the end is of the holes you drill? You do now, with Robit’s new measuring tool, The Robit® Sense Systems – ‘M’ Series, a complementary product for Robit’s measurement technology offering. Measuring is now easier and faster than ever. Measurement can be done right after drilling a hole. You can see a 3D view of the drilled hole in the drilling pattern immediately in the field through a tablet computer and anywhere through Sense Systems cloud service.
When drilling holes in rock, the holes often turn away from the desired direction, and in long holes the deviation may be even several meters. Hole deviation results in inefficient operations on a site and in the worst case may create hazards. The new system measures the actual straightness of drill holes, so the information can be utilized in optimizing and charging a rock face.
As the results are visible immediately after measuring, it is possible to react to any hole deviation when positioning and directing the following holes or when charging the holes. Since the system utilizes accelerometers, gyroscopes and/or compass technology, it can be used in all types of rock formations – even in magnetic ore.
Optimizing charging raises efficiency in blasting by:
- Optimizing crushing aggregates through controlled charging and blasting, no oversized boulders
- Ensuring safe blasting without the risk of flying rocks
- Increasing the overall productivity of the blasting and crushing process
- Cutting costs for explosives and reducing downtime
- Storing all drilling data in a database to develop your drilling process
- Raising overall efficiency
Technical facts:
- Basic configuration of the measuring tool comprises a measuring module embedded in an aluminum probe, 30 meters cable with one meter markings designed for extreme conditions and a rugged tablet computer with user interface.
- 100 meters cable available as an accessory.
- The technology which utilizes high accuracy accelerometers, gyroscopes and compasses also makes it possible to measure in magnetic ore.
- The accuracy is ±0,5° for inclination and ±1° for azimuth, when used in accordance with Manual Guidelines.
- The diameter of the probe is 38mm.
- Easy and quick on-site calibration of the compass with graphical guidance, recommended yearly calibration at Robit factory.
