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

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

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.
