Product Description

Product Description
TUNGSTEN CARBIDE INSERT BITS

2. Structures

1. Cutting structure this type TCI tricone bits:
The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.

2. Gauge structure this type TCI tricone bits:
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.

3. Bearing structure of this type TCI tricone bits:
High precision bearing with two thrust faces. Ball lock the cone. Hardfaced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved.

4. Seal and Lubrication of this type TCI tricone bits:
Premium O-ring, optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase

The lubricating reliability.

5. Product Application of this type TCI tricone bits:
It can receive high WOB in the conventional drilling. It is suitable for various formations by matching cutting structure with different tooth shape, tooth density and tooth exposure heig
