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.
