A tool turret according to the invention comprises a turret head which is shiftable between a rotational position and a working position, drive means adapted to rotate the turret head in the rotational position and being in permanent engagement with the turret head, fixation means for locking the turret head in the working position, and a transducer sensing the position of the turret head. The turret head is rotatable with respect to a non-rotary body which is axially displaceable with the turret head and which has a circumferential projection serving as a piston and being mounted axially displaceable in an annular recess serving as a cylinder and formed in a seat, receiving the body, of a member supporting the body. The projection and the annular recess cooperate with each other to ensure axial displacement of the body with the turret head between the rotational position and the working position. The transducer is fixedly connected to and axially displaceable with the body and is adapted to sense the relative angular position between the body and the turret head.
