437

Soft Formation TCI Tricone Bits

The 437 TCT 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, result in high bit penetrate one rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.

517

Medium Formation TCI Tricone Bits

The 517 features aggressive chisel tungsten carbide insert on the heel rows and inter rows. This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard for-mationes. The HSN rubber O-ring provides adequate sealing for bearing durability.

637

Hard Formation TCI Tricone Bits

The 637 bits can be used to drill hard and abrasive forma-tions . Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-durability and long life.

617

Medium-Hard Formation TCI Tricone Bits

The 617 feature robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fest drilling rate and added cutting structure durability in medium to medium hard formation. The HSN rubber O-rin provides adequate sealing for bearing durability .
