1.Main 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 locks the cone. Thrust faces hard face with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
