1.Material: carbide
2.Various types for different formations
3.Cutting structure: The durability of premium tungsten carbide insert is improvedwith new formulas and new techniques for insert bit
4.Gauge structure: Multiple gauge protection with trimmers on the heel of cone,tungsten carbide inserts and hard facing on the shirttail increases gaugeholding capability and bearing life
5.Seal and Lubrication: Premium O-ring, optimal seal compression and curved sealstructure can enhance the seal performance. The compensator system and advancedgrease can greatly increase the lubricating reliability.
6.Bearing Structure: High precision bearing with two thrust faces. Ball looks thecone. Hard faced head bearing surface inlaid with friction-reducing alloy andthe silver-plated. Abrasion insistence and the silver-plated. Abrasioninsistence and seizure resistance of the bearing are improved.
7.Product application: It can receive high WOB in the conventional drilling. It issuitable for various formations by cutting structure with different tooth shape,tooth density and tooth exposure height.
