                        characteristic
Soft formation 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 Oring provides adequate
sealing for bearing durability.
