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.

100% diamond enhanced heel row inserts provide maximum durability in extremely abrasive applications. The bit will drill longer intervals of full gauge hole, and eliminate the need for expensive reaming operations.

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.
