Abstract
A drilling tool has a shifting unit including a rotatable shifting lever (6) with a shifting cam (9) for switching between different operating positions corresponding to different operating speeds. For holding the shifting lever (6) in the operating positions, a spring clip (14) is mounted on the lever and is rotatable relative to the tool housing. The spring clip has detents (14a, 14b) arranged to snap into recesses (1d, 1e) in a bolt-like part of the housing which rotationally supports the shifting lever (6).
