Description

TCI 8-1/2 Inch 216mm Three Cone Tricone Roller Bit Oil Well Drilling In Blue

1.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.

2.Bearing Structure

High precision journal bearing with two thrust faces.Balla lock the cone.Hardfaced head bearing surfaces.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure resistance of the bearing are improved.

3.Seal and Lubrication

Premium HNBR 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 rellability.

4.Recommended Drilling Parameters

IADC WOB (weight on bit dia) RPM(R/Min) Application Formation
