Tool support with a collet chuck receiver

Abstract

A tool support for fixed or rotating tools embodied with a collet chuck receiver for a collet chuck for clamping a tool shaft from the direction of the tool side. The collet chuck receiver has a tapering bore for receiving a collet chuck and a coaxial screw thread assigned to the bore for receiving a tensioning nut. In place of a collet chuck, a tool clamping insert is inserted with a tapering receiving neck into the tapering receiving bore, wherein the tool clamping insert is clamped in place by fastening means from the direction of the tool side.
