13 3/4 TCI tricone bit IADC417 TCI tricone bit Cover all all IADC code Certified by ISO9001&API 13 3/4 TCI tricone bit IADC417IADC417 TCI tricone bit INTRODUCTION1. Sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased.2. Thrust bearing surfaces are hardfaced and treated with friction reducing technology.3. All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.4. Ball locked cone, suitable for high rotary speed.5. New type of wear resistant grease that can sustain high temperature up to 250°C is utilized. 1.Cutting Structure of this type sealed and non-sealed tci tricone bits :

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 type tci tricone rock bits :

Multiple gauge protection with gauge trimmers on the 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 type tci tricone rock bits :

High precision roller bearing with two thrust faces. Ball lock the cone.Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
