A machine tool comprises a spindle stock (12), a tool magazine (20) in which a plurality of grippers equipped with tool holders are arranged to travel along an endless track, and two gripper arms (25, 26; 28, 29) arranged for moving the tool holders between a common pick-up and/or mounting position at the tool magazine and a spindle position at the spindle nose of the spindle stock (12), which has a vertical spindle axis (23, 24). In order to achieve the narrowest possible arrangement for the transfer movement between the pick-up and mounting position and the spindle position, it is provided that both gripper arms (25, 26; 28, 29) operate simultaneously and in opposite directions between their spindle positions and their pick-up and/or mounting positions, which are located on one side of the spindle stock (12), moving along geographical curves evading each other.
