Abstract
The tool comprises a casing (12) which contains an electric motor (11) connected to a tool holder (17) via a gear box (14) and a torque sensitive clutch (15), (16), (21), (22). The tool also includes switch means operable to cut off the motor when a torque above a predetermined value is transmitted across the clutch. The switch means includes a Hall effect device comprising a stationary Hall effect element (43) and a magnet (37) movable with a rod (32) in response to operation of the torque sensitive clutch.
