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

Backreaming cutters are strategically positioned to improve hole quality & ensure trouble free tripping

Diamond enhanced inserts maintain hole integrity and the short gauge length optimizes directional control.

Large junk slot area maximizes the efficiency of cuttings removal for optimum hole cleaning.
