Specifications1>Meet with API Spec7-1 &ISO 9001:2008 2>Good quality andafter-sale service 3>30 years experience in it.

TCI tricone bit(high toughness and durability suitable for different rock formation)

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:

Multiplegauge protection with gauge trimmers on the heel and gauge inserts onthe gauge surface of the cone, tungsten carbide inserts and hard facingon the shirttail increases gauge holding capability and bearing life.

3. Bearing Structure of this type tci tricone rock bits :

Highprecision roller bearing with two thrust faces. Ball locks the cone.Thrust faces hard face with wear resistant alloy. Abrasion resistanceand seizure resistance of the bearing are improved.
