Abstract
A chuck for the clamping of tools by shrink fit includes a chuck member which has a longitudinal section having a central receptacle with clamping surface for the insertion and holding of the tool to be clamped with its shank. The longitudinal section includes a plurality of segments arranged at distances from one another in the circumferential direction and separated from each other by clearances in between, the segments extending essentially axially parallel and forming the clamping surface with their inner peripheral areas. The segments are surrounded on the outside by a sleeve part. The segments are either in one piece with the sleeve part or, as separate structural elements, are a component of a mounted insert.
