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.
