 TCI Tricone Bits 415 Soft Formation TCI Tricone Bits1)The  415 tci bits are used to drill low compressive strength, very soft formations.

2)TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection.

3)This cutting structure design, combined with maximum cone offset, results in high bit penetration rates.

4)The deep intermesh of cutter rows prevents bit balling in sticky formations  .

TCI Tricone Bits 535 Medium Formation TCI Tricone Bits1)The  535 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. 2)This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard formations.

3)The HSN rubber O-ring provides adequate sealing for bearing durability.
