Product Description
HJ series highly reliable roller cone bit
Tricone bit introduce
1. Tricone bit cutting structure
Adopting new formula of new technology of the high quality hard alloy tooth, enhance the cutting teeth mechanical properties.
2. Tricone bit diameter structure
Using multiple gage protection structure: Die with multidrug trimming tooth (GT teeth), round back, claw back set have cemented carbide gear, surfacing resistance mo alloy, strengthen ZhaoJian and anterior apply welding, greatly improving the drill gage protection ability.
3. Tricone bit bearing structure
Adopting high precision with radial sliding, two way thrust bearings, ball tight.
