TCI tricone bit
Soft Formation TCI Tricone Bits
The 437 TCI bits are used to drill low compressive strength, very soft formations.
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.
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 formation. The HSN rubber O-ring provides adequate
sealing for bearing durability.
Hard Formation TCI Tricone Bits
The 637 bits can be used to drill hard and abrasive formation. 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.
Medium-Hard Formation TCI Tricone Bits
The 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-ring provides adequate sealing
for bearing durability.
