Cutting Structure
The wear-resistance of the teeth is enhanced with premium tungsten
carbide hardfacing on the tooth surfaces for the steel tooth
bit.The durability of premium tungsten carbide inserts is improved
with new formulas and new techniques for insert bit
Gauge Structure
Multiple gague protection with gauge trimmers on the heel and gauge
inserts on the gauge surface of the cone,tungsten carbide inserts
and hardfacing on the shirttail increases gauge holding capacity
and bearing life.
Bearing Structure
High precision journal bearing with two thrust faces,Balls lock the
cone.Hardfaced head bearing surface.Cone bearing inlaid with
friction-reducing alloy and then silver-plated.Abrasion resistance
and seizure of the bearing are improved.and suitable for high
rotary speed
Seal and Lubrication
The advanced metal seal package consists of two metal seals and two
elastic energizers.Compressed energizers ensure good contact being
kept on two sealing surfaces of metal rings by elastic force,and
achieves the bearing seal.In the drilling,metal seals are
relatively dynamic,and the energizers are static.This will improve
the reliability and durability of bearing seal.The pressure
compensator system and advanced grease can greatly increase the
lubricating reliability.
