12 1/4" IADC 825 Jet Air Tricone Rock Bit

The tricone bit is a common drilling bit with a wide range of uses and high mechanical drilling speed.

It is a bit body consisting of three roller cones assembled and welded together and fitted with a connecting screw.

The teeth of a tricone drill bit can be adapted to various types of formations by choosing different designs and types of bearing according to the hardness of the formation.
