Product Description
Advantage
Bearing Structure
High precision journal bearing with two thrust faces. Ball locked 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, and suitable for high rotary speed.
Cutting Structure
Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit. Widened crest insert improved the bit aggressivity and penetration rate.
Gauge Structure
The multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection.
