1) Tri-cone Bit Cutting Structure 
Adopting new formula of new technology of the high quality hard alloy tooth, enhance the cutting teeth mechanical properties. 
2) Tri-cone Bit the 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 and anterior apply welding, greatly improving the drill gage protection ability. 
3) Tri-cone Bit Bearing Structure 
Adopting high precision with radial sliding, two ways 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. 
4) Tri-cone bit Seal Lubricants

Adopting advanced metal sealed, greatly extend the drill life. 
5) Tri-cone Bit Products Applicable
Metal seal bit stable performance, than common rubber seal bit longer life, suitable for underground power drill and high penetration rate turntable drilling.
