ROBIT ® EVOLUTION SERIES ROBIT ® EVOLUTION SERIES Further. Faster.

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 formations, have witnessed masses...

Bench & Production Drilling In the medium to large sizes significant performance strides were taken by diving deep into flushing properties. Here in particular, the computational fluid dynamics (CFD) simulations proved their strong added value as they drove the pre-test phase for fast finding of optimal solutions and truly significant impacts. The 76-mm Retrac button bit superbly exemplifies the new design aspects. The Retrac body itself has the signature Robit curving grooves and the sleek geometry flows through to the new face design. The simulations clearly show that the new model isn’t...
