Abstract
A chuck for a tool comprises a device for supplying a cooling and/or lubricating medium to a medium channel in a tool held in the chuck, an adjusting screw, and securing means. The adjusting screw serves as a stop for the tool held in the chuck, is arranged in the chuck, is adjustable in relation to the chuck in the axial direction of the chuck, and interacts with a pipe element. The pipe element is held rotatably in the chuck and the securing means limit an axial displacement of the pipe element at least in the direction of the adjusting screw. The pipe element and the adjusting screw are connected in a rotationally fixed but axially displaceable manner with respect to each other.
