Product Description


Kingdream TCI Tricone 8 1/2'' Rock Roller Bit/ Rock Bit
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.

4. Tricone bit seal lubricants
Adopting advanced metal seal, greatly extend the drill life.

5. Tricone bit applicable
Metal seal bit stable performance, than common rubber seal bit longer life, suitable for underground power drill and high penetration rate turntable drilling. <o:p>
