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

The short gauge pad length enhances steerability. Combined with the short trimmer lengths of the gauge inserts, these characteristics promote gauge retention and maximize steering efficiency.

Turbine sleeves reduce vibration and hole spiraling in turbine applications. This feature increases bit life and enables the bit to achieve maximum ROP
