Product Details

Product Description

Cutting Structure: The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

Gauge Structure: Multiple 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.

Sealed Bearing Structure: 1.Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.
2.The advanced metal seal package will improve the reliability and durability of bearing seal
