Cutting Structure

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

Gauge Structure

Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the

shirttail increases gauge holding capability and bearing life.

Bearing Structure

High precision bearing with two thrust faces. Ball 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.

Seal and Lubrication
