Drill rig parts Tungsten carbide insert tricone bit/tricone drill bit for oil field/water well

The wear-resistance of teeth is enhanced with premium tungsten carbide

 hardfacing on the tooth surfaces for steel tooth bit.

 Multiple gauge 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 capability and bearing life.

1.Abrasion resistance and seizure resistance of the bearing are improved.
2.Premium O-ring, Optimal seal compression and curved seal structure

 can enhance the seal performance.
