To install a tool, place the desired milling cutter in a collet that fits the shank of the cutter. Insert the collet into the spindle. Ensure that the key way on the collet mates properly with the key in the spindle. While holding the tool with one hand, start the threads of the draw bar into the collet by hand.
Mill drills are a lighter alternative to a milling machine. These combine a belt driven drill press with the dual coordinate abilities of the milling machine's table for flexibility and efficiency. A locking collet prevents the cutting tool from falling away from the spindle when lateral forces are experienced against the bit.
