A workpiece holding collet is provided with at least one tool receiving aperture located in each collet segment. A changing tool having mating fingers is inserted into the collet, when it is in its compressed condition in a chuck. The chuck is then opened, releasing the collet, so that the interior sidewalls of the apertures frictionally engage the tool fingers inserted therein, thereby locking the collet to the changing tool. The tool is provided with a handle so that an operator may now remove the collet and then store the collet together with the tool.
