Bit design is available with ONYX fixed cutters for improved thermal stability in harder, more abrasive formations, resulting in greater wear resistance.

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

Turbine sleeves reduce vibration and hole spiraling in turbine applications. This feature increases bit life and enables the bit to achieve maximum ROP
