Description of tricone bit
{1) Cutting Structure of this series tricone rock
bit :
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.The
wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
(2) Gauge Structure of this series tricone rock bit :
Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts
and hardfacing on the shirttail increases gauge holding capability and bearing life.

(3)Bearing Structure of this series tricone rock bit :
High precision bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with
friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and
suitable for high rotary speed.
(4)Seal and Lubrication of this series tricone rock bit :
The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact
being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal are
relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. The pressure
compensator system and advanced grease can greatly increase the lubricating reliability.
