<p>The invention relates to a tool coupling for connecting a tool carrier wh ich can be driven in a rotating manner, in particular a milling tool with a machine spindle or an adapter connected to a spindle, wherein four drivers i n a crosswise formation are provided for transmitting torque between the sai d parts and in the clamping state engage in four recesses. To allow the tool coupling to be easily operated and to be of a simple construction, and also to counteract undesired jamming, it is proposed that the drivers respective ly have on the side transmitting the torque a planar face which lies with fu ll surface-area contact against a wall of a groove-shaped recess in the clam ping state, that on the opposite side the driver has a smaller positively or frictionally engaging contact with the wall there of the groove-shaped rece ss and that a quick-acting clamping device is provided for the axial clampin g of the tool carrier and the spindle or an adapter.</p> |
