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.
