Bit design and performance have been certified through the validation process prescribed by IDEAS simulation technology.

The PX feature places thermally stable diamond inserts (TSP) on the gauge to maximize gauge retention and extend bit life.

The ONYX 360 rolling cutter feature allows the PDC element to rotate enabling the full circumference of the diamond edge to be utilized. This prevents a wear flat developing in only one place thereby maintaining cutter sharpness for improved drillbit durability.

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.
