A power tool (10) comprises a main body (12) having a motor driven tool (24) extending from a first front end of the main body, and has a first handle (18) integrally formed on the main body to be remote from this front end. A second support handle (20) is pivotally mounted on the tool body (12) to be pivotally displaceable about a pivot axis (34) so as to be displaceable from a first position in which a grip (22) of the support handle is disposed forwards of the first handle (18), to a second position wherein the grip member (22) is disposed rearwardly of the first handle (18). Also disclosed is the use of restraining means engageable between the support handle (20) and the main body (12) for releasably restraining the handle in either of the first or second positions. Further disclosed is a dual switching mechanism requiring operation of a switch on the main handle (18) and also on the grip (22) of the support handle (20) to allow operation of the tool, irrespective of whether the handle (20) is in its first or second position.
