Normal IADC Code Tricone Roller Bit:
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, results in high bit penetration 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 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 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 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.
617 Medium-Hard Formation TCI Tricone Bits:
The 617 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.
