<p>A punch tool is mounted within a tubular portion of a tool-carrier by means of two separable half-shells which engage over the shank of the tool. The shells are retained within the tool-carrier by means of a pin extending transversely therethrough. The tool-carrier is reciprocable within a bore of a support member, and the pin has a head engaged in an axial groove in the bore.</p> |
