2.Reliable bearing system
3.long working experience
commodity:12 1/4 tricone bit
1.material:carbide
2.various types for different formations
3.cutting strucuture:The durability of premium tungsten carbide insert is improved with new
formulas and new techniques for insert bit
4.Guage structure:Multiple gauge protethion with trimmers on the heel of cone,tungsten carbide
inserts and hard facing on the shirttail increases gauge holding capability and bearing life
5.seal and lubracation:Premium O-ring,optimal seal compression and curved seal structure can enhance the seal performance.The compensator system and advanced grease can greatly increase the lubricating reliability.
6.Bearing Structure:High precision bearing with two thrust faces.Ball look the cone.Hardfaced head bearing surface inlaid with friction-reducing alloy and the silver-plated.Abrasion insistance and the silver-plated.Abrasion insistance and seizure resistance of the bearing are improved.
7.Product application:It can receive high WOB in the conventional drilling.It is suitable for various formations by cutting structure with different tooth shape,tooth density and tooth exposure hight.
