Bit design and performance have been certified through the validation process prescribed by IDEAS simulation technology.

The Stinger's unique conical geometry delivers high point loading to fracture tough-to-drill formations more efficiently.

Placed on the blade, Stinger conical diamond elements offer improved impact resistance when drilling through inter-bedded formations or when hard inclusions such as chert or conglomerates are encountered.

Bit design is available with RockStorm PDC technology. These all-in-one cutters break the paradigm and provide ultimate wear resistance and ultimate impact resistance in the same PDC cutter. As a result, faster drilling rates are delivered while increasing overall run length.

Placing thermally stable diamond inserts (TSP) on the gauge maximizes gauge retention and extends bit life.
