17 1/2 IADC635 ROCK BITS

1. Metal-face sealed bearing TCI Bit

Cutting Structure

The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

Gauge Structure

Multiple gauge protection with gauge trimmers on 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.

Sealed Bearing Structure

1.Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.
2.The advanced metal seal package will improve the reliability and durability of bearing seal.

2. Elastomer sealed bearing TCI Bit
Cutting Structure	The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.The Tricone bit field is composed of a shallow sequence of sediments of fluvial origin, in which sandstone channels contain heavy oil with gravity ranging from 11 to 13°
Gauge Structure	Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Sealed Bearing Structure	1.Abrasion resistance and seizure resistance of the bearing are improved. 2.Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance.
