Products details
1>Cutting Structure
The durability of premium tungstencarbide insert is improved with new formulas and new techniques for insert bit.
2>Gauge Structure
Multiple gauge protection withgauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing onthe shirttail increases gauge holding capability and bearing life.
3>Bearing Structure
High precision bearing with twothrust faces. Ball lock the cone. Hardfaced head bearing surface. Cone bearinginlaid with friction-reducing alloy and then silver-plated. Abrasion resistanceand seizure resistance of the bearing are improved.
4>Seal andLubrication
Premium O-ring, Optimal seal compression and curved sealstructure can enhance the seal performance. The pressure compensator system andadvanced grease can greatly increase the lubricating reliability.
5>Product Application
It can receive high WOB in theconventional drilling. It is suitable for various formations by matching cuttingstructure with different tooth shape, tooth density and tooth exposure height.
