A torque arm (13), possibly a telescopic torque arm (10), for holding a power tool (16), the torque arm having a connection end (28) for connecting the torque arm (10) to a hand held power tool (16). An innermost tubular arm member (13) of the torque arm (10) includes an outer tubing (18) of a fibre reinforced polymer and an inner tubing (17) of a metal material. The outer tubing is adapted to withstand normal operational forces. The inner metal tubing (17) is arranged inside the outer fibre reinforced polymer tubing (18) as a safety measure in order to avoid a clean break of the torque arm (10, 13) if the outer tubing (18) would rupture. |
