<p>The present invention relates to a chuck including a sleeve (1; 1'), a tool-receiving part (3; 3'; 3'; 3'') as well as a coupling part (5; 5'; 5'; 5''), the tool-receiving part (3; 3'; 3'; 3'') and the coupling part (5, 5'; 5'; 5'') being made integrally, alternatively from a plurality of joined pieces, that the tool-receiving part (3; 3'; 3'; 3''), in the area for the end thereof turned from the coupling part (5; 5'), has an axially extending recess (7; 7'; 7'; 7''), which is intended to receive a tool (9; 9'; 9'; 9''), and that the sleeve (1; 1') consists of a separate element. The chuck according to the present invention is distinguished in that the tool-receiving part (3; 3'; 3'; 3''), in the area for the recess (7; 7'; 7'; 7''), is externally cone-shaped, that an internal limiting wall (10; 10') of the sleeve (1; 1') is cone-shaped, and that the cone angle for the tool-receiving part (3; 3'; 3'; 3'') and the interior limiting wall (10; 10') is substantially equally large and so small that it is self-inhibiting.</p> |
