Characteristics of Cone Structure1.Cutting StructureThe durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.2.Gauge StructureMultiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.3.Bearing StructureHigh precision bearing with two thrust faces. Balls lock the cone.Hardface heard 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.
