TCI bits series
IADC 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.

Soft Formation TCI Tricone Bits
The 437 TCI 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 penetratione rates.The deep intermesh of cutter rows prevents bit bailing in sticky formations.

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 strcture durability in medium-to-medium hard for-mationes.The HSN rubber O-ring provides adequate sealing for bearing durability.

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 formations.The HSN rubber O-rin provides adequate sealing for bearing durability.
Steel tooth bits series
IADC 114-117
Soft Formation Tooth Bits
The 114-117 bits are used to drill low-compressive strength,soft formations.Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible.Wear -resistant hard facing is used to control tooth wear.On the softest bit types this hard facing completely covers the bit teeth.

IADC 127
Medium-Hard Formation Tooth Bits
The 127 bits are used to high-compressive strength,medium hard formations.Short projection teeth with reduced crest length are used in this series of bits designs.Durable hard facing is applied to reduce tooth wear
