Abstract:
An electric tool may include a tool main body configured to be able to mount a battery pack. The tool main body may include an electric motor, a controller for controlling the electric motor, and a centrifugal fan rotatably driven by the electric motor for producing a flow of air. The controller may be positioned such that the flow of air produced by the centrifugal fan is applied to at least a part of the controller.
