TCI 437 Soft formation TCI Tricone bits

The 437 tci bits are used to drill low compressive strength very soft formation tci bits maximize
the use of both conical and chisel tungsten carbide inserts of large diameters and high projection.
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.

TCI 517 medium formation TCI Tricone bits

The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows 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.

TCI 617
TCI tricone bits 617 features robust chisel tungsten carbide inserts on the heel row and conical
on the inner rows .this design provides a fast drilling rate and added cutting structure durability in
medium to medium hard formations . the HSN rubber o-rin provides adequate sealing for bearing durability .
TCI 637 can be used to drill hard and abrasive formations
wear –resistant tungsten carbide inserts 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.
