ROBIT EVOLUTION SERIES Applying the most advanced technology to the toughest drilling applications across the globe Over 30-year history of Robit has only seen one thing constant – the ever-increasing need for the connection between hammer and rock to endure more severe forces. In recent years, top hammer performance development has not only been linear but exponential, as maximum impact powers in e.g. tunneling and drifting applications rise above 40 kW and impact frequencies steadily reach beyond 100 Hz. The Robit Button Bits, now used across the globe in a vast variety of rock...

ROBIT EVOLUTION SERIES Drifting & Tunnelling In the small end, development focused especially on the specific needs of high power and high frequency drilling in tunneling and drifting applications. Different variants were extensively tested with our customers and set against conventional hard rock bits. In the end, the best results were gleaned from modifications and optimization to face design, but particularly from increasing both gauge and face button numbers as well as increasing the number of flushing holes. The test results of the Evolution bit in hard Scandinavian granite were very...

Considering all the above, it is safe to say the reality of drilling has not changed. We are going deeper with more speed and force, driving the development of the entire drilling consumables industry. As an established global company, we continuously need to reinvent ourselves. Across the globe, our cases are more versatile, our knowledge base wider, our questions and tools for finding answers smarter. We are confident that we are better than anyone else. In the end, we fight hard every day to be the strongest and smartest when it comes to the space between drill and rock. That is the...

ROBIT® CODES Green Steel All of the Robit button bits are manufactured of new 100 % recyclable steel. In the environment-friendly steel production process, the CO² emissions have been reduced by 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. All the products are available with ballistic or SuperDome buttons. Specially designed for Robit Better fatigue resistance 100 % recyclable 80 % less CO² emissions Process smoke filtrated...
