Introduction

Tungsten Carbide Inserts tricone bit is also called tci tricone bit. Because of its versatility and performance, it's still one of the main Rock Bits in use today. It is widely used for oil&gas, water well, geotechnical, environmental, geothermal, construction, exploration and mining drilling.

1)      Cutting structure

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

2)      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.

3)      Sealed Bearing structure

There are four types of bearing, standard open roller bearings, sealed roller bearings, sealed journal bearings, and air blast/cooled bearings. The sealed bearing can be divided into rubber/elastomer sealed bearing and metal-face sealed bearing. It can provides an advanced wear resistance by maintaining the optimum position within the bearings. 

4)      Hydraulic and lubrication system

The pressure compensator system and advanced grease can greatly increase the lubricating reliability. High-efficiency hydraulic system and lubrication system provide power and guarantee the long life.
