437
Soft Formation TCI Tricone Bits
The 427 tci bits are used to drill low compressive strength,very softformations .TCI bits maximize the use of bothconical and chisel tungsten carbideinserts of large diameters and high projection.This cutting sstructuredesign,combined with maximum cone offset,results in high bit penetration rates.The deep intermesh of cutter rows prevents bit bailing in stickyformations.
517
Medium Formation TCI Tricone bits
The 517features aggressive chisel tungsten carbide inserts on the heel rowsand inner rows.This desing provides a fast drilling rate and added cuttingstructure durability in medium-to –medium hard formations .The HSN rubber o-ringprovides adequate sealing for bearing durability.
637
Hard Formation TCI Tricone Bits
The 637bits can be used to drill hard and abrasive formations .Wearresistanttungsten carbide inserts are used in the outer rows to prevent loss of bitgauge.Maximum numbers of bemisphericalshaped inserts are used in all rows toprovide cutter durability and long life.
617
Medium-Hard Formation TCI Tricone Bits
The 617features robust chisel tungsten carbide inserts on the heel row andconical on the inner rows.This design provides a fast drilling rate and addedsutti8ng structure durability in medium to medium hard formations .The HSNrubber o-ring [rovodes adequate sea;omg fpr bearomg dirability.
