1.Cutting Structure
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques
2.Gauge Structure
Mutiple gauge protection with guge trimmers on the heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on shirttail increases gauge holding capability and bearing life.
3.Bearing Stucture
High precision joumal bearing with two thrust face.Balls lock the cone.Hardfaced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure resistance of the bearing are improved,and suitable for high rotary speed.
4.Seal and Lubrication
Advanced metal face seal ;owers sea; frictional force and improves seal life.The pressure compensator system and advanced grease can greatly increase the lubricating reliablity.
5.Six-Point Position Stablization Structure
The bit leg designed with specific integrated stablization structure,which provides near six-point contact with borehole wall for the bit.This new feature gives the bit unequaled stability which greatly reduces bit vibration,protects the cutting sructure from damaging blows and keeps good borehole quality.The thickened nozzle wall can protect hydraulic from the wear and fluid erosion.
6.Product Application
It is suitable for downhole motor and hign speed applications,and is the ideal selection for drilling directional and horizontal.
