Description :

Roller cone bits have rollers rotating around bearings. Roller cone bits use steel teeth or tungsten carbide inserts as cutting elements.
A roller cone bit removes rock by crushing, gouging and scraping.
Roller cone bits are made up of three legs welded together.
Each leg holds a rolling cone fitted with teeth or inserts. Teeth are milled directly in the cone where tungsten carbide inserts are pushed in holes that are drilled in the cone.
Roller cones that have teeth milled into them are called tooth bits. These steel teeth are brazed over with a protective hard facing which substantially increases the life of the bit. Steel tooth bits are mainly used for fast soft rock applications like surface bits or shallow wells. When the cutters are made from tungsten carbide inserts, the bit is called a TCI (tungsten carbide insert) bit. TCI bits are more durable but are not as aggressive as a steel tooth bit. TCIs are used in harder more abrasive applications.

Cutting Structure
Unique steel tooth structure effectively improving the wearing resistance of the
teeth and greatly increasing the rate of penetration.

Gauge Structure
Enhanced gauge protection with hard facing on the shirttail, strength enabled
with special insert tungsten carbide.

Bearing Structure
High precision journal bearing, hard-faced bearing surface. Cone bearing inlaid
with friction-reducing alloy and then silver-plated, made the rotating more
stable, safe, and durable.

Seal and Lubrication
The patented unique metal seal can enhance the seal performance, it has longer
durability than the rubber seal. The compensation bearing grease system greatly
increases the lubricating reliability and improve the bearing life effectively.
