Advanced fabric composite seals and specialized high temperature grease designed with improved heat and wear resistance to enhance bit life at elevated temperatures.

Diamond enhanced heel inserts maintain gauge in abrasive, hard formation drilling and significantly increase cone durability. This feature extends bit life and ensures that a full gauge hole is drilled.

The PS feature offers strategically placed clusters of semi-round top (SRT) shaped carbide inserts that maximize leg protection, prevent bit wear, and substantially increase bit life in abrasive formations.
