Robit RG drill rods gain ground in Swedish quarries
In 2024, we introduced the RG51 shoulder-driven drill rod – a Top Hammer design where the shoulder, rather than the thread, takes the impact. This results in higher stiffness, straighter holes, and a longer service life than conventional C(T)-series rods. Today, the RG rod family is well on its way into the Nordic market.
With RG45 now joining RG51 and RG60, Robit can offer a complete range of shoulder-driven rods for bench drilling and quarrying. Sweden, through long-time distributor Eurodrilling, is among the first countries where the RG45 and RG51 systems are being actively used and tested.
Field trials have been carried out at several sites, with two experienced blasting contractors standing out as early adopters: Bohus Bergsprängning and Alingsås Sprängtjänst. Both operate demanding rock-drilling jobs where tool life, hole straightness, and reliability are closely monitored.
At Bohus Bergsprängning’s quarries, RG45 rods (3,660 and 4,265 mm) and RG45 bits (76, 83, and 89 mm) have been running in daily production since spring 2025. In midsummer, Robit’s Sales Manager Santeri Sillanaukee and Drillmaster Harri Piispanen, together with Eurodrilling’s Bosse Bäckgren, followed performance on site. Bohus Bergsprängning has already noticed the difference in performance and moved from trials to regular RG45 usage.
In October 2025, Alingsås Sprängtjänst hosted a demo day at its premises in Alingsås. After a short introduction to Robit and the RG concept, the team mounted RG45 rods and bits on the customer’s rig and drilled test holes in a nearby rock. The results were so convincing that Alingsås Sprängtjänst decided to start using RG45 right away.
The Swedish experiences so far mirror Robit’s earlier field data from Finland, where RG45 rods have regularly achieved service lives of over 50% and, in some cases, more than 70%, longer than those of standard C45 tools. Users also report straighter holes thanks to the stiffer shoulder-driven connections, better penetration when combining RG rods and RG bits, and noticeably easier uncoupling, all of which translates directly into less downtime and more drill metres per shift.
“We see Sweden following the same trend as Finland, where the Robit RG45 and RG51 systems are becoming the new standard in bench drilling and quarrying. These products truly speak for themselves and help our customers drill better. Day in and day out”, says Sales Manager Santeri Sillanaukee.
To support growing demand, Eurodrilling has begun stocking RG rods and RG bits in Sweden and expects volumes to increase further as the RG concept continues to win new users, carving out a stronger position for Robit in the Swedish Top Hammer market.
