TCI bits series:
1) .Soft formation TCI triconebits:
The soft formationTCI tricone bits are used to drill low compressive strength, very softformations. This bit maximized to use of both conical and chisel tungstencarbide inserts of large diameters and high projection. This cutting structuredesign, combined with maximum cone offset, results in high bit penetrationrates. The deep intermesh of cutter rows prevents bit bailing in stickyformations.
2) .Medium formation TCI tricone bits:
The medium formationTCI tricone bits features aggressive chisel tungsten carbide inserts on theheel rows and inner rows. This design provides a fast drilling rate and addedcutting structure durability in medium to medium hard for mations. The HSNrubber O-ring provides adequate sealing for bearing durability.
3) .Hard formation TCI tricone bits:
The hard formationTCI tricone bits can be used to drill hard and abrasive formations. Wearresistance tungsten carbide inserts are used in the outer rows to prevent lossof bit gauge. Maximum numbers of hemispherical shaped inserts are used in allrows to provide cutter durability and long life.
4) .Medium hard formation TCI tricone bits:
The medium hardformation TCI tricone bits features robust chisel tungsten carbide inserts onthe heel row and conical on the inner rows. This design provides a fastdrilling rate and added cutting structure durability in medium to medium hardformations. The HSN rubber O-ring provides adequate sealing for bearingdurability.
