The Stinger element features a highly distinctive conical geometry with a thick synthetic diamond layer, engineered to resist high impact loads and abrasive wear for superior durability.

The center location of the Stinger conical diamond in the bit enhances its stability to mitigate whirl and other artifacts that waste energy and reduce ROP. The Stinger element also provides an efficient mechanism to drill the very center of the borehole.

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