Abstract: A portable power tool having a plate tool (30), in particular a sanding plate or polishing plate, and a drive motor, arranged in a machine housing, for driving the plate tool into an oscillating and/or rotating and/or eccentric movement of a machining surface of the plate tool, wherein the portable power tool is able to be guided with the machining surface in a main working direction forwards and to the side transversely to the main working direction in at least one transverse working direction in order to sand or polish a workpiece surface, wherein the portable power tool has a covering device for the plate tool, said covering device having at least one protective wall which is disposed upstream of at least one lateral surface, extending next to the machining surface, of the plate tool with regard to the main working direction and/or the transverse working direction in order to protect against contact with obstacles.

Abstract: A saw device, in particular a circular table saw or a miter saw, including a saw unit with a saw blade and a support structure, which can be placed with its underside on a base and has a workpiece support on which a workpiece can be placed while it is being sawn with the saw device. The saw device has a coupling interface via which a releasable, vertically tension-proof coupling with at least one system box can be produced in order to form a vertical stack together with the at least one system box in such a way that the saw device assumes a transport orientation in the vertical stack in which transport orientation the workpiece support is vertically oriented with its support plane.
