Abstract: A hand power tool (10), in particular with integrated dust removal, that comprises a housing (12) on which a dust tube (22) is mounted that is capable of being interconnected with a dust box (24) by means of its dust inlet connection piece (26), whereby a side wall (27) of the dust box (24) has through holes (25) that are reached over by a filter in dust-tight fashion, becomes less expensive and more environmentally friendly by the fact that the filter (30, 31, 32, 33, 34, 35, 36, 37, 38, 300) is formed by a flat sheet composed of a fine-pored material, the surface area of which is increased by means of certain structures.

Abstract: An electrical power grinder, in particular an eccentric grinder, is disclosed that has a grinding wheel (14) and a grinding-medium holder (23), held on the underside thereof, of soft material. For the sake of reducing wear of the grinding-medium holder (23) at its outer edge and lengthening the service life of the grinding-medium holder, the grinding wheel (14) is provided with an edge guard, which has a guard member (30) encompassing the grinding wheel (14) that protrudes, in the plane of the grinding wheel, past the outer contour of the grinding-medium holder (23) (FIG. 3).

Abstract: A dust and chip removal device for sanding hand power tools has a storage container securable to a hand power tool, a transport channel via which dust and chips are directed into the storage container, a retaining element preventing the dust and chips from flowing back out of the storage container, the retaining element having at least one passage, an elastic element which has a holding force closing the at least one passage, the passage being openable automatically against the holding force at starting at a certain delivery pressure, while the elastic element automatically closes the passage below a certain delivery pressure, and a channel having cross-sectional area which tapers toward the passage.

Abstract: The invention is based on a dust and chip removal device, in particular for sanding hand power tools (10), having a transport channel (12, 14), via which the dust and chips can be directed into a storage container (16) secured to the hand power tool (10) in particular, and having a dust and chip retaining device that comprises a retaining element (18, 20, 22, 24) to prevent the dust and chips from flowing back out of the storage container (16).

Abstract: A hand power tool (10), in particular with integrated dust removal, that comprises a housing (12) on which a dust tube (22) is mounted that is capable of being interconnected with a dust box (24) by means of its dust inlet connection piece (26), whereby a side wall (27) of the dust box (24) has through holes (25) that are reached over by a filter in dust-tight fashion, becomes less expensive and more environmentally friendly by the fact that the filter (30, 31, 32, 33, 34, 35, 36, 37, 38, 300) is formed by a flat sheet composed of a fine-pored material, the surface area of which is increased by means of certain structures.

Abstract: A manual machine tool (10) includes a vacuum device for dust removal (19) situated in its housing (12) and a blow-out connection (20) installed after this. A dust collection box (21), particulaily self-contained, can be attached in detachable fashion to the blow-out connection (20) via its blow-in connection (22). The dust collection box (21) is airtight on all but two sides and has air-exit holes (40) on the top side (36) and a dustproof filter element (48)—especially a fluted filter—on the inside. The dust collection box is particularly secure against the unintentional escape of dust after the dust collection box is detached from the associated manual machine tool because a pair of sealing lips (500) arranged as a separate part is provided inside the blow-in connection (22), which pair of sealing lips (500) is connected as a single part with closing flaps (520, 520) projecting into the interior of the dust collection box (210).
