A shrink-fit chuck having a receiving body, a receiving opening for a tool shank, arranged in the receiving body, an accumulation and collection chamber arranged in the front region of the receiving opening and at least one coolant supply channel leading to the accumulation and collection chamber. The accumulation and collection chamber is delimited to the front by a ring bar arranged at the front end of the receiving opening. The internal diameter of the ring bar is adjusted to the internal diameter of the receiving opening in such a manner that as small an annular gap as possible exists between the ring bar and the tool shank. A plurality of outlet openings are provided in the ring bar for discharging to the outside a coolant routed via the coolant supply channel into the accumulation and collection chamber.
