A quick-change collet is disclosed with a tool holding insert, fitted in a collet sleeve and with a locking device releaseable by an outer sleeve for retention and driving the insert in the collet sleeve. The outer sleeve is rotatably journalled on the insert and the bearing is so connected with the insert that the insert accompanies the outer sleeve when this is used as a hand hold to move the insert with tool out from the collet or to place it in the collet.
