IADC 637 Tricone Bit

Cutting Structure

Conic&chisel insert improved the bit aggressivity and abrasive resistance.Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit.

Applications

Medium to hard with high compressive formations, abrasiveness formations such as sandstone, limestone, dolomite ,hard gypsum, marble, etc

 

Tricone drill bit Features

Seal and Lubrication

The bearing seal is adapting the high quality HNBR O-ring. The better seal compression and the radial seal structure can enhance the seal performance. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.

Bearing Structure

High precision journal bearing with two thrust faces. Ball locked 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, and suitable for high rotary speed.

 

Gauge Structure

The multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection.
