IADC tricone roller cone classification system
4 character code, first 3 characters are numbers, the last is a letter
1st number is the series. 1 to 3 represent a milled tooth tri cones, 4 – 8 represent TCI tri cones. The higher the series number the harder more abrasive the rock formation is.
2nd number is the relative degree of hardness within a series. The number ranges from 1 – 4, the higher the number the harder the formation
3rd number represents bearing design and gauge protection.
Open bearing
Roller bearing air cooled
Open bearing gauge protected
Sealed roller bearing
Sealed roller bearing gauge protected
Sealed friction bearing
Sealed friction bearing gauge protected
4th character is a letter and describes optional features. There are 16 alphabetic character's each representing the tricones most significant feature
437
Soft Formation TCI Tricone Bits china oil tools
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.
