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

The geometry of conical inserts is optimized to reduce insert breakage and maximize ROP in WOB sensitive formations.

Use of the inclined chisel insert on the gauge row minimizes breakage, maintains a full gauge wellbore and provides faster ROP for a longer period of time.

Diamond enhanced gauge inserts eliminate gauge wear in abrasive and hard-formation applications, and allow the bit to drill at a faster ROP for longer periods of time.
