摘要：
A tool clamping insert has a tool holder for receiving a tool shank. The tool holder hole is nominally smaller than the tool shank to be therein but upon heating of the insert expands to a size permitting insertion of the tool shank and, upon cooling, shrink fitting therein. The insert has an external clamping surface and is positioned in a clamping unit. The clamping surface and the tool holder hole are each configured with diameters, external and internal respectively, that change along the progression of their axial lengths.
