Cutting Structure
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
Gauge Structure
Multiple gauge protection with gauge trimmers on the heel and gsuge inserts on the gauge suifame 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.Hard faced head bearing suiface.
Cone bearing inlaid with friction-reducing alloy then silver plated.Abrasion resistance and seizure resistance of the bearing are improved.
Seal and Lubrication
Premium HNBR O-ring ,optimal seal compression and curved seal structure can enhance the seal performace.The pressure compensator system and advanced grease can greatly increase the lubrication
reliability.
Product Application
It can receive high WOB in the conventional drilling.It is suitable for various formations by matching cutting
structure with different tooth shape ,tooth density and tooth exposure height.
