The receiver (1) has a chuck (2) i.e. contraction fodders, including a coupling section (3) for setting the chuck into a tool machine. A tool is provided with liquid and/or gaseous cooling medium injected into a hole and arranged in a central region of the receiver parallel to a central hole. An undercut includes large diameter, and is arranged in depth of the central hole, where the undercut forms an annular chamber around a shaft that is inserted into the central hole. The chamber is injected and partial tangentially penetrated in the hole to form an inlet opening for the medium. The receiver includes a sleeve-type cap (13) that is made of plastic material or metal. |
