[origin: EP2116333A1] The drill (1) has a pressure piston (16) mounted in a tool spindle (5), and a retaining ring (23) axially supported at a side turned towards a riveting set (17) over a non-return disk (28) at a ring stage (30) of the spindle. The retaining ring is axially supported at a side turned towards a hammering body over a retaining disk (29) at a locking ring (31). The locking ring is inserted in an annular groove (32) formed at the spindle. The retaining ring, the retaining disk and the non-return disk are mirror-symmetrical with respect to a center plane running perpendicular to a spindle axis (9).
