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.

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