Cutting Structure
The durability of premium tungsten carbide insert is improved with new formulas and
new techniques and new techniques. The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces.
Bearing Structure
Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the
cone which reduces the probability of cone ropping to minimum.
Product Application
It is suitable for the shallow well, water well and geothermal well.
Sealed Steel Tooth Tricone Bit
Cutting Structure
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth
surfaces for steel tooth bit.
Gauge Structure
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.
Bearing Structure
High precision roller bearing with two thrust faces. Ball lock the cone.Thrust faces hardface with
wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
Seal and Lubrication
Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance.
The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
Product Application
It is suitable for various formations, and achieves high RPM under low to medium WOB application
