Abstract (en)
[origin: EP0302295A1] In the case of tools which have a working zone and a clamping zone, the clamping zone should not be hardened during the heat treatment. This is achieved by means of a holding device which consists of a metal of good thermal conductivity, contains blind holes for insertion of the tools and is provided with all-round thermal insulation. <IMAGE>
