A double profile drawing tool includes a mandrel having a profile drawing die formed therein with first and second portions extending in opposite directions, associated therewith. The mandrel is disposed in a supported surrounding manner within a structure including a housing body and an embedding component. The embedding component is securely fixed within the housing body by way of a support plate which is joined to the housing body in a shrink fit manner. The structure formed by the housing body, support plate, with the mandrel and embedding component contained therein, is then securely mounted within a U-shaped outer housing member. First and second tapered openings are formed on opposite sides and along the longitudinal axis of the double profile drawing tool, such tapered openings providing communication to the first and second portions of the profile drawing die from opposite directions. The double profile drawing tool can be reversed for operation in an opposite direction once it has been determined that one portion of the profile drawing die has been worn. In either direction of operation, the mandrel is positively supported so as to prevent movement and to insure that a substantial portion of loading forces are directed away from the profile drawing die.
