HJT437

It is used for low compressive strength and exceeding soft formation of high drillability, such as, shale, clay, sandstone, soft limestone, halite, gypsum etc

Its structure is Large-diameter side top row of teeth within the spoon-shaped, and wedge-shaped outer row of teeth. Its teeth are different height and the margin is not different distance, also it increases a row of trimming teeth between the back conical teeth and outer row of teeth.

0.35~0.90

TCI Tricone Bits 415
Soft Formation TCI Tricone Bits
The FL 415 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 balling in sticky formations

TCI Tricone Bits 535
Medium Formation TCI Tricone Bits
The FL 535 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 formations. The HSN rubber O-ring provides adequate sealing for bearing durability.

TCI Tricone Bits 625
Medium-Hard Formation TCI Tricone Bits
The BW 625 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.

TCI Tricone Bits 735
Hard Formation TCI Tricone Bits
The BW 735 bits can be used to drill hard and abrasive formations. 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.
