A machine tool having automatic tool changing apparatus including a tool storage magazine formed with a plurality of circumferentially spaced socket recesses each having a generally U-shaped tool support shoe that is adapted to be broken away from the magazine to prevent damage to the tool changing apparatus in the event of unintended overtravel of the tool transfer mechanism at the magazine during a tool change operation. Limit switch means are provided for interrupting the feed drive of the machine in the event of such unintended overtravel of the tool transfer mechanism.
