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.

Stress relieved core is fractured by central indenter yielding improved ROP

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.

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

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