The holder (12) has a conical retaining surface (18) i.e. retaining cone (26), for retaining and driving by a drive spindle (16). Integrated fluid paths (28, 30a, 30b) conduct operating fluid e.g. coolant. Blocking elements (50, 52a, 52b) e.g. non-return valves, are associated to the fluid paths. The blocking elements block or release the fluid paths based on a direction and a pressure of the operating fluid. The blocking elements include a defined passage direction and a defined blocking direction. The fluid paths are directly or indirectly connected with each other. |
