Normal IADC:

437 Soft Formation TCI Tricone Bits:

Designed for low compressive strength, very soft formations, the 437 TCI bits are equipped with large diameter conical and chisel tungsten carbide inserts. This innovative cutting structure, coupled with maximum cone offset, achieves high penetration rates while preventing bit bailing in sticky conditions through deep intermesh cutter rows.

517 Medium Formation TCI Tricone Bits:

The 517 is engineered with aggressive chisel tungsten carbide inserts on both the heel and inner rows, delivering fast drilling rates and enhanced cutting structure durability. This is especially effective in medium to medium-hard formations, supported by an HSN rubber O-ring for reliable bearing durability.

637 Hard Formation TCI Tricone Bits:

Optimized for hard and abrasive conditions, the 637 bits feature wear-resistant tungsten carbide inserts in the outer rows to maintain bit gauge, while hemispherical-shaped inserts are distributed across all rows to ensure cutter durability and extended lifespan.

617 Medium-Hard Formation TCI Tricone Bits:

Featuring robust chisel tungsten carbide inserts on the heel row and conical inserts on the inner rows, the 617 is designed for rapid drilling rates and superior cutting structure durability in medium to medium-hard formations. The inclusion of an HSN rubber O-ring guarantees effective sealing for bearing longevity.
