A tool turret has a housing and a revolving head which can be fixed in different rotational positions by means of an arrangement of toothed rings. A locking device includes a cam drive for the selective releasing and fixing in position of the gear teeth. In order to configure the tool turret simply and to save space, an axially movable, annular locking part is provided with axial gear teeth and has one part of the cam drive in the form of a curvilinear aperture. The middle sections of the curvilinear aperture are straight and side parts extend obliquely. A guide member penetrates the curvilinear aperture as the other part of the cam drive. The teeth cooperating with the teeth on the locking part are mounted on the revolving head and on a stationary toothed ring.
