FEATURES: Carbide version of our popular P bush, for high-production applications. PC bushes are permanently pressed into the jig plate, usually flush with the top surface. They are generally used for single-operation drilling or reaming, when you do not expect to replace bushes during the tooling's lifetime. PC bushes can be mounted closer together than headed bushes, but offer less resistance to heavy axial loads.
