Abstract
Improved composite tools, such as punches and dies, which tools have very high and abrasion resistant working surfaces. The composite tool includes a relatively soft support, such as a tool steel body, and a relatively hard working portion, such as a carbide, which is firmly mounted within the support in such a manner that axial and radial shocks are dampened.
