1.Cutting Structure: The wear-resistance of teeth is enhanced with premium tungsten carbide hard-facing on the tooth surfaces for steel tooth bit. The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
2.Gauge Structure: Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone , tungsten carbide inserts and hard-facing on the shirttail increases gauge holding capability and bearing life.
3.Bearing Structure: High precision roller bearing with two thrust faces .Balls lock the cone. The leg bearing can get larger by arranging the rollers in groove of the cone hole, so it can receive more WOB ,and suitable for high RPM. Thrust faces hard-faced with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
