An electric tool creates a gentle cooling air outlet current through formed in a housing outlet window. In the housing is rotatably provided a radial fan, in order to cool a heated motor. From the radial fan cooling air is generated by the outlet window, is omitted. Each outlet window has a rectangular shape with an upstream and downstream side in the direction of rotation of the cooling fan. A chamfered region is at least on the upstream side, and in an inner circumferential surface of the housing is provided, so that a thickness of the housing wall as claimed in the direction of rotation is reduced and, after. The area on an enlarged scale ungefaste an effective area of the window for the outlet of air.
