TCI tricone bit(high toughness and durability suitable for different rockformation)
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 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 insertson the gauge surface of the cone, tungsten carbide inserts and hard facing onthe 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 andseizure resistance of the bearing are improved.
