    摘要: A rotating chuck (10) includes a coolant groove arrangement (26) integrally along a shank-receiving bore (16) of the rotating chuck (10). The groove arrangement (26) defines a flow path in fluid communication with front and rear bore ends (20,22). The groove arrangement (26) includes one or more slanted groove portions (32) opening out to, and being inwardly inclined towards, a front chuck end (12) of the rotating chuck (10).

Arranged between the recess (30) and the peg (100) is a bayonet-type closure having at least one protrusion (106, 115) that is present on the peg (100). Arranged in the first subassembly (20) is a clamping element (60), the front end of which butts against one of the protrusions (106, 115) during clamping. The present invention provides an interface which ensures, for each tool change, easy handling together with high repeatability with regard to the position of the mutually contacting subassemblies.
