Abstract:
A drilling and/or chipping tool has a locking sleeve (9) axially displaceable through a first axial length (A1) and a second axial length (A2). When the locking sleeve (9) is axially displaced through the first length (A1) a rotationally fixed connection between a tool bit holder (10) and a housing (1) of the tool is interrupted. If the locking sleeve is displaced by the second length (A2) the tool bit holder (10) can be removed from the tool.
