What is Tricone Rock Bit consists of?
- A roller cone or tricone rock 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.
- 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.
- Three types of cemented carbide inserts are used for roller type bits being Chisel, Conical, and Hemispherical.
- A roller bit will utilize nozzles from which the compressed air escapes to lift the cuttings from the bottom of the hole.
