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.
