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

Binary carbide gauge places wear resistant semi-round top carbide inserts between the primary gauge inserts to enhance gauge retention in transitional drilling. This substantially improves gauge durability and allows longer in-gauge bit runs.

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.

Vectored extended nozzles combine increased hydraulic energy with more precise orientation, bringing the flow area closer to the gauge/drive row and hole bottom for improved cleaning and cuttings removal. This maximizes cutting structure efficiency and increases ROP.
