Product Description
Tricone Drill Bit
8 1/2" S537G tricone drill bit original CS brand of tungsten carbide drill rock bit for oil well drilling
A tricone bit is a mechanical drill bit located in the bottom hole assembly. The bit cuts away the surface of the rock being
drilled through rotation and mechanical friction caused by the teeth of the bit. Tricone bits are designed to take the energy of the rotating drill string and the supply of mud and to apply this force to deepen the well.
