TCI bits series:
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 O-ring provides adequate sealing for bearing durability.

Steel teeth bits series:
Soft formation teeth bits:
The soft formations tooth bits are used to drill low compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetrations rates possible. Wear resistance hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth.
Medium hard formations tooth bits:
The medium hard formation tooth bits are used to drill high compressive strength, medium hard formations. Shoot projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.
