Available sizes: From 2 7/8 to 26"


Bearing type: Sealed bearing and non-sealed bearing
Metal sealed journal bearing
Rubber sealed journal bearing
Cutting structure: The back cone and the teeth all surface is are hardfaced strengthening, improved steel tooth shape and welding materials, showing teeth higher

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. Tooth claw big shaft neck and two stop surface welding have wear-resisting alloy, cone big hole and two stop surface solution and silver inlaid special alloy, increase the abrasion resistance and resistance bearing vice occlusive ability, improve bearing ability of high speed vice adapt.
