Tricone drill Bit 10-5/8inch IADC 635 with Tungsten Carbide Insert

Tricone Drill Bit Feature

Soft Formation TCI Tricone Bits:

The Tricone Rock Bit 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 Tricone Rock Bit 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 rubber O-ring provides adequate sealing for bearing durability.

Hard Formation TCI Tricone Bits:

The Tricone Rock Bit 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 Tricone Rock Bit 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 rubber O-ring provides adequate sealing for bearing durability.
