Abstract:
Hand-held machine tool having an outer housing extending substantially along a longitudinal axis, with an electric drive unit accommodated in this outer housing, and with a tool arrangement which is disposed at a first end of the electric drive unit. The outer housing of the machine tool has a defined inner contour and the electric drive unit and the tool arrangement have a defined outer contour. The outer contour and the inner contour of the outer housing are at a predetermined minimum spacing from each other. At least one inlet opening for cooling air is disposed in an end region of the outer housing. The electric drive unit drives a fan arrangement which draws in through the at least one inlet opening cooling air which flows substantially parallel to the rotational axis of the electric drive unit through the machine tool and flows out of the outer housing to the outside at the outer contour of the machine tool.
