TCI tricone bits:
The soft formation TCI tricone bits are used to drill low
compressive strength, very soft formations. This bit maximized to
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 medium formation TCI tricone bits 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 for mations. The HSN rubber
O-ring provides adequate sealing for bearing durability.
Hard formation TCI tricone bits:
The hard formation TCI tricone bits can be used to drill hard and
abrasive formations. Wear resistance 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 medium hard formation TCI tricone bits 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.
