IADC TCI Tricone Bit Roller Bit Rock Bit for Well Drilling

1.CUTTINGSTRUCTURE
The durability of premium tungstencarbide inserts is improved with new formulas and new techniques for insertbit.The wear-resistance of teeth is enhanced with premium tungsten carbidehardfacing on the tooth surfaces for steel tooth bit.

2. GAUGESTRUCTURE
Multiple gauge protection with gaugetrimmers on heel and gauge inserts on the gauge surface of the cone, tungstencarbide inserts and hardfacing on the shirttail increases gauge holdingcapability and bearing life.

3.BEARINGSTRUCTURE
High precision bearing with two thrustfaces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaidwith friction-reducing alloy and then silver-plated. Abrasion resistance andseizure resistance of the bearing are improved and suitable for high rotaryspeed.
4.SEAL AND LUBRICATION
Theadvanced metal seal package consists of two metal seats and two elasticenergizers. Compressed energizers ensure good contact being kept on two sealingsurfaces of metal rings by elastic force, and achieve the bearing seal. In thedrilling, metal seal are relatively dynamic, and the energizers are static. Thiswill improve the reliability and durability of bearing seal. The pressurecompensator system and advanced grease can greatly increase the lubricatingreliability.
