Abstract
A clamping device has a collet or a sleeve that contains an inner coolant supply. The non-through parts of the clamping device have formed therein radial slits and/or intermediate slits that open at the machine side and/or the tool side of the shank of the device. The slits and non-through parts of the device are arranged in such a way that they form a coolant barrier.
