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.
