High Drilling Efficiency Tri cone Drill Bit / 17 1/2 TCI Tricone Bit

17 1/2 Tri Cone Drill Bit Discription

Tri Cone Drill Bit Feature

Cutting Structure

The wear-resistance of the teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for the steel tooth bit. The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit

Gauge Structure

Multiple gague protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hard facing on the shirttail increases gauge holding capacity and bearing life.

Bearing Structure

High precision journal bearing with two thrust faces, Balls lock the cone. Hard faced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure of the bearing are improved. and suitable for high rotary speed

Seal and Lubrication

The advanced metal seal package consists of two metal seals and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieves the bearing seal. In the drilling, metal seals are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.

Tri Cone Drill Bit Application

It is suitable for down hole motor and high speed applications

Main features

1. The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for steel tooth bit.
