High Energy bits were refined and enhanced to add durability and drilling rate to withstand applications where the bit weight and rotary speed are at the high end of the spectrum delivering better performance in these critical operating parameter applications.
Features / Benefits
Patented Bearing Seal
A patented conical seal gland design handles pressure fluctuations better and still maintains a preferred dynamic location and interface for the seal. The design is also complimented by a heat shield that is deployed between the seal and inner bearing. This shield provides lower seal operating temperatures leading to longer seal life.
Engineers developed a bearing system to support higher loads which resulted in a more robust and tighter tolerance journal bearing.
A new anti-shale packing configuration is incorporated, improving cuttings diversion away from the mud side of the seal gland.
Increased Wear Resistance
New shirttail hard metal that significantly increased wear resistance in critical areas of the bit has been added.
