A tool magazine for an automatic machine producing various machining operations with the aid of machine tools held by a machine spindle. The magazine for replaceable tool is adapted to hold a plurality of tools each in tool holding mechanisms being held on a tool pallet mounted on a rotary table of the automatic machine. The spindle cooperates with the magazine so as to be in alignment with a tool holding mechanism of the magazine at a tool replacement position; whereby a new tool can be withdrawn from the tool holding mechanisms by the spindle or a used tool held by the spindle can be inserted into the tool holding mechanism. In addition, the magazine is indexed, to align the several tool holding mechanisms, one at a time, with the spindle at the tool replacement position by transmitting spindle movement, preferably through a tool, to the magazine. The magazine may include a plurality of magazine units, each carrying several tool holding mechanisms on a supporter adapted for rotation about a shaft in response to defined spindle movement. Releasable lock mechanisms prevent non-commanded support rotation.
