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.

Low Exposure (MDOC – Managed Depth Of Cut) Cutter backing raised to minimize excessive depth of cut because of formation heterogeneity to reduce cutter loading and minimize torque in transitional drilling. Minimizes cutter breakage and extends bit life.
