Custom Form Tool

This is a cutting tool designed for use on a horizontal CNC in preparation for threading. It is machined from A2 tool steel and will accept standard indexable carbide inserts. The part is first drilled undersized with a conventional twist drill. This tool is used to finish the minor diameter, cut a thread-relief and chamfer the opening, all in a single pass. The part is then threaded with the appropriate size tap to finish the threading operation.
