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 extends PDC bit life by reinforcing its gauge areas with diamond-enhanced inserts (DEI) set in highly wear-resistant tungsten carbide.

Bit design is available with advanced ONYX cutter technology. This includes the next generation ONYX II cutters that have superior abrasive wear and exceptional resistance to thermal degradation, enhancing cutter durability for increased footage drilled and faster ROP.
