The invention relates to a shrinking device (1) for shrinking a rotary tool (5) into a central receiving opening of a toolholder (3) which holds said rotary tool (5) in a press fit. The device comprises an induction heating device (15, 18) for thermally expanding the toolholder (3) in the area of the receiving opening. A cooling device (51, 53) with at least one cooling collar (53) which can be placed on the toolholder (3), in physical contact with the same, and through which a liquid coolant can flow, is provided for cooling the receiving opening area of the toolholder. This liquid cooling considerably reduces the overall time span needed for the shrinking process.
