IADC Code Series Tricone Bits Features:
114-117, 127
Soft Formation Tooth Bits
The 114-117 bits are used to drill low-compressive strength, soft
formation. 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 bits type this hard facing completely covers the bit teeth.
127
Medium-Hard Formation Tooth Bits
The 127 bits are used to drill high-compressive strength, medium
hard formations. Short projection teeth with reduced crest length
are used in this series of bit designs. Durable hard facing is
applied to reduce tooth wear.
437
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.
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 strcture 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 formations. The HSN rubber O-rin provides adequate
sealing for bearing durability.
