1.Cutter Structure The durability of premiun Tungsten carbide inserts is improved with new formulas and new techniques 2.Gauge Structure Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inders and hardfacing on the shirttail increases gauge holding capacity and bearing life. 3.Bearing Structure High Precision jourmal bearing with two thrust faces. Balls lock the cone. hardfaced head bearing surface. cone bearing inlaid with friction-reduceing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved,and suitable for high rotary speed. 4.Seal and Lubracation Advance metal face seal lowers seal frictional force and overall seal torque and improves seal life. the pressure compensator syste, and advanced grease can greatly increas the lubracating relaibility. 5.Six-Point Position stabilzation Structure The bit leg is designed with specific interated stability structure, which provides near six-point contact with borehole wall for the bie. this new feature gives the bit unequaled stability which greatly reduces bit vibration protects the cutting structure from damageding blows and keeps good borehole quality, the thickened nozzle wall can protecy hydraulic system from wear and fluid erosion. 6. Product Application It is suitable for downhole motor and high speed applications, and is the ideal selection for drilling directional and horizontal wells.
