Normal IADC:

437 Soft Formation TCI Tricone Bits:

The 437 TCI bits excel in penetrating low compressive strength, extremely soft formations. With a cutting structure of large, protruding conical and chisel tungsten carbide inserts, combined with maximum cone offset, they ensure high penetration rates, while deep cutter row intermesh prevents bit bailing in sticky terrains.

517 Medium Formation TCI Tricone Bits:

The 517 TCI Tricone Bit is designed with aggressive chisel tungsten carbide inserts on both heel and inner rows, providing fast drilling rates and enhanced durability for medium to medium-hard formations. The HSN rubber O-ring offers exceptional bearing sealing, ensuring extended durability.

637 Hard Formation TCI Tricone Bits:

The 637 TCI Tricone Bits are tailored for drilling in hard, abrasive formations. Equipped with wear-resistant tungsten carbide inserts on outer rows to maintain bit gauge, and numerous hemispherical-shaped inserts in all rows, these bits promise long-lasting cutter durability and extended bit life.

617 Medium-Hard Formation TCI Tricone Bits:

The 617 model features robust chisel tungsten carbide inserts on the heel row and conical ones on inner rows, delivering fast drilling rates and enhanced cutting structure durability for medium to medium-hard formations. The HSN rubber O-ring ensures sufficient bearing sealing for longevity.
