Description of drill bit
Roller cone bit consists of a bit body with three moveable conical rollers equipped with cemented carbide inserts. The idea is the crush the rock by rolling the inserts against the rock with appropriate rotation speed and feed force. Three types of cemented carbide inserts are used for roller type bits being Chisel, Conical, and Hemispherical. Carbide inserts are distributed over the three rollers in such a manner that the entire bottom of the hole is worked on when the drill bit is rotated. Roller bits for hard and abrasive rock generally have spherical cemented carbide inserts closely spaced. Roller bits for softer rock may have the chisel and conical carbide teeth or quality milled steel teeth as the cutters. A roller bit will utilize nozzles from which the compressed air escapes to lift the cuttings from the bottom of the hole.
IADC 7 SERIES DRILL BITS
The medium hard formation TCI tricone bits features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows.
This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations.
The HSN rubber O-ring provides adequate sealing for bearing durability.
Bits thread are manufactured according to API standards.
