Zusammenfassung:A rotary spindle (4) for a power tool such as a hammer drill is disclosed. The spindle (4) comprises a first spindle part (402) for rotation about its longitudinal axis by means of a motor and having an inwardly directed rim (406), and a second spindle part (404) for supporting a drill bit of the hammer drill and having an outwardly directed rim (410). The second spindle part (404) extends through an aperture (408) in the first spindle part (402) and rims (406,410) cooperate with each other to prevent removal of the second spindle part (404) from the first spindle part (402). A circlip (414) locks the first and second spindle parts (402,404) together and maintains o-rings (412) under compression.
