TCI Tricone Bit (Tungsten Carbide Three Cone Bit), TCI Rock Bit for Oil Well Drilling


IADC 4 SERIES TCI Tricone bit
These bits are used to drill low compressive strength, very soft formations. The bits maximize the use of both conical and chisel 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 balling in sticky formations.

IADC 5 SERIES TCI Tricone bit
These bits are used to drill low compressive strength, soft to medium soft formations. Drill bit design features are used to enhance bit penetration rates. Some reduction in cone offset and insert projection is used to improve cutter durability. Insert numbers and pitch is controlled to prevent tracking.

IADC 6 SERIES TCI Tricone bit
These bits are used to drill high-compressive strength, medium hard formations. A small amount of cone offset and low insert projection is used to prevent cutting structure damage when hard streaks are encountered. Increased numbers of blunter, smaller diameter inserts are used to increase life in harder, more abrasive formations.

IADC 7 SERIES TCI Tricone bit
These bits are used to drill hard and abrasive formations. A more wear-resistant grade of tungsten carbide insert is used to prevent wear. Low cone offset with increased numbers of breakage resistant cutters add to the required bit durability.

IADC 8 SERIES TCI Tricone bit
These bits can be used to drill extremely hard and abrasive formations. Wear-resistant 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.
