The annular body (11) has inwardly open blind holes which serve as cylinders (10), are arranged in a star pattern and into which pistons (9) connected to the jaws (8) are inserted, it being possible to move the pistons radially towards the centre by means of a pressure fluid. The inner tool, which is designed as a stop ring (6), has individual stops which are formed by stop heads (3) with threaded shanks (4), which are screwed in radially adjustable fashion into radial threaded bores (5) of the stop ring (6) and, at the end of the shank, have means (7) for turning the threaded shank (4). <IMAGE>
