ABSTRACT:
In a hand held power operated percussion tool, the housing (10) is vibration insulated from the impact mechanism to protect the operator from unhealthy vibration forces. In order to form a vibration damped gripping member at or in front of the forward end of the tool housing (10), a sleeve element (20) is supported on the housing (10) for axial adjustability thereon. The sleeve element (20) surrounds the working implement (18) and prevents the operator from using the latter as a grip means. The sleeve element (20) is arrestable in any desired axial position by a conical lock nut (22) threadingly engaging the sleeve element (20) and forming therewith a radially acting clamp.
