Overview:
·The wear-resistance of the teeth is enhanced with premium tungsten caride hardfacing on the toth sufaestfor the stetooth bit .The drabilty of premium tngsten carbide inserts is improved with new formulas and new tehniques for insert bit.
Multple gauge prtecton with gauge trimmers on the heel of cone,tungsten carbides inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
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 resistance of the bearing are improved.
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.
Milled and T.C.I pilot tricone bits of common sizes and full toth shapes are in ready stock, always ensuring supply of most proper and suitable tricone bits for our customers.
The rubber seal, composite seal and metal seal can be chosen for bearing structure, result in different bearing lifetime. We can supply reasonable match of products due to different drilling condtions, effectively controlling cost of drling tools.
