Tricone Drill Bit features

 

1. Cutting Structure of this type sealed and non-sealed TCI tricone bits :

The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing 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 hard-facing 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 hard-face with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
