• an electronic control and regulation unit for controlling and/or regulating the electric motor;
• wherein the electronic control and regulation unit establishes a first operating mode, in which the electric motor operates at a first frequency, and wherein the electronic control and regulation unit establishes a second operating mode, in which the electric motor is operated at a second frequency,
• wherein an operating mode is switchable by a switch actuatable by the operator of the tool between the first operating mode and the second operating mode,
• wherein the rotational speed of the electric motor is higher in the second frequency than in the first frequency, and
• wherein the tool comprises a load display, in which a power of the tool is displayed on the basis of a current drawn by the electric motor during operation,
