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.

V-Flo™ directs nozzles to the leading side of the following bit cone to maximize cleaning. The resulting upward spiral flow enhances bottom hole cleaning, prevents bit balling and allows the bit to drill at maximum ROP.

Spinodal 2 bearing with silver plated components ensures longer runs at higher ROP. This proprietary material offers maximum wear resistance and withstands extreme load forces for longer periods than conventional bearing materials.
