Bit design is available with RockStorm PDC technology. These all-in-one cutters break the paradigm and provide ultimate wear resistance and ultimate impact resistance in the same PDC cutter. As a result, faster drilling rates are delivered while increasing overall run length.

Increased cleaning, cooling, and cuttings evacuation with available hydraulic flows; high flow rates with minimal increase in pump pressure, and reduced risk a bit balling.

Backreaming cutters are strategically positioned to improve hole quality & ensure trouble free tripping

Diamond enhanced inserts maintain hole integrity and the short gauge length optimizes directional control.

Large junk slot area maximizes the efficiency of cuttings removal for optimum hole cleaning.
