Abstract
A power tool () with a housing () that includes a dust box () and a motor () with air cooling, and a cooling exhaust-air duct () and a chip suctioning duct () which guides a chip-suctioning flow can be used with improved performance and in an environmentally friendlier manner due to the fact that the cooling air flows across the dust box () under favorable flow conditions, whereby the evacuation of dust into the dust box () is improved and whirls of dust caused by cooling air in the tool region are prevented from forming.
