TCI bits series
437
Soft Formation TCI Tricone Bits
This cutting structure design,combined with maximum cone offset,results in high bit penetration rates.The deep intermesh of cutter rows prevents bit bailing in sticky formations .
517
Medium Formation TCI Tricone Bits
This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard formations .The HSN rubber O-ring provides adequate sealing for bearing durability.
637
Hard Formation TCI Tricone Bits
The 637 bits are used in the outer rows to prevent loss of bit gauge .Maximum numbers of hemispherical shaped inserts are used in all rows to provide cutter durability and long life .
617
Medium-Hard Formation TCI Tricone Bits
This design provides a fast drilling rate and added cutting structure durability in medium to medium hare formations .The HSN rubber O-rin provides adequate sealing for bearing durability.
description of drill bit:
(1)Bearing Structure of this series tricone rock bit :
High precision bearing with two thrust faces. Balls lock the cone.Hardface 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.
(2)Seal and Lubrication of this series tricone rock bit :
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.
