Abstract

A machine tool, in particular a hand-held machine tool, is disclosed. The machine tool includes at least one housing unit and at least one drive unit arranged within the housing unit. The machine tool further includes at least one separator unit which is provided to divide at least one fluid flow directed through the housing unit into at least two sub-flows, in particular according to a density of foreign bodies. One sub-flow of the sub-flows has a higher density of foreign bodies in comparison to another sub-flow of the sub-flows. The machine tool also includes at least one fluid cooling unit which is provided for cooling the drive unit by way of the at least two sub-flows.
