Tricone bit 12 1/4", TCI Tooth For Hard Rock Formation Oil Hole
Drilling
Product Description:
TCI Bit/Tricone Rock Bit/Drill Bits
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.
