3 7/8" IADC637C Tricone Rock Bit

TCI Roller Cone Bit

Drill bit introduce
1. Drill bit cutting structure
Adopting new formula of new technology of the high quality hardalloy tooth, enhance the cutting teeth mechanical properties.

2. Drill bit diameter structure
Using multiple gage protection structure: Die with multidrugtrimming tooth (GT teeth), round back, claw back set have cementedcarbide gear, surfacing resistance mo alloy, strengthen ZhaoJianand anterior apply welding, greatly improving the drill gageprotection ability.

3. Drill bit bearing structure
Adopting high precision with radial sliding, two way thrustbearings, ball tight. Tooth claw big shaft neck and two stopsurface welding have wear-resisting alloy, cone big hole and twostop surface solution and silver inlaid special alloy, increase theabrasion resistance and resistance bearing vice occlusive ability,improve bearing ability of high speed vice adapt.

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

5. Drill bit applicable
metal seal bit stable performance, than common rubber seal bitlonger life, suitable for underground power drill and highpenetration rate turntable drilling.
