Product Description
Tricone Drill Bit 8-1/2 Inch TCI Drilling Tool IADC 537
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.

Tricone Bit Cutting Structure
Unique steel tooth structure effectively improving the wearing resistance of the teeth and greatly increasing the rate of penetration.
Tricone Bit Gauge Structure
Enhanced gauge protection with hard facing on the shirttail, strength enabled with special insert tungsten carbide.
Tricone Bit 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.
Tricone Bit 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.
We supply different sizes of this type of bit as clients’requirement.
