Rockmore launches new drill bit design
Aug. 15, 2012 – Rockmore International has a new drill bit design especially suited for hard rock quarry drilling.
The CrossFlow design is intended to provide more efficient rock cutting flushing in order to improve penetration rates and extend bit life. The flush holes are located within newly designed flushing grooves that promote maximum flow of rock cuttings away from the bit face. These V-shaped flush grooves are much wider at the bit edge than conventional designs and greatly enhance the ability of the flushing medium to carry the larger rock chips away from the bit face and up towards the hole annulus. In addition, the rock chip velocity is reduced at the wider section of the flush groove at the bit edge, leading to a reduction of steel erosion on the body of the bit.
