Product Description

Product Description

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.
 

Product Features

1. High-strength and high-toughness carbide teeth are used to improve the impact resistance of the teeth and reduce the tooth breakage rate;
2. The optimally designed tooth row number, tooth number, exposed tooth height and unique alloy tooth shape give full play to the cutting ability and cutting speed of the drill bit;
3. Widely used in petroleum exploration, mining exploration, geothermal wells, hydrological exploration and other fields.
