Product Description
Tricone roller rock bit
1)Cutting Structure
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit. The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for steel tooth bit.
2)Gauge Structure
Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hard facing on the shirttail increases gauge holding capability and bearing life.
3) Bearing Structure
High precision bearing with two thrust faces. Balls lock the cone. Hard face heard 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.
4)Seal and Lubrication
The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal 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.

IADC Tricone Bit classification system
4 character code, first 3 characters are numbers, the last is a letter
1st number is the series. 1 to 3 represent a milled tooth tri cones, 4 8 represent TCI tri cones. The higher the series number the harder more abrasive the rock formation is.
2nd number is the relative degree of hardness within a series. The number ranges from 1 4, the higher the number the harder the formation
3rd number represents bearing design and gauge protection.
1Open bearing
2Roller bearing air cooled
3Open bearing gauge protected
4Sealed roller bearing
5Sealed roller bearing gauge protected
6Sealed friction bearing
7Sealed friction bearing gauge protected
4th character is a letter and describes optional features. There are 16 alphabetic character's each representing the tricones most significant feature.
