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.

Gauge pad configuration for very abrasive formation. This additional diamond volume will help prevent the gauge pads from going under gauge.

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