A manual machine tool (10) with a vacuum device for dust removal (19) situated in its housing (12) and having a blow-out connection (20) installed after this, to which a dust collection box (21), particularly self-contained, can be attached in detachable fashion via its blow-in connection (22), which dust collection box (21) is airtight on all but two sides, with the dust collection box (21) comprising air-exit holes (40) on the top side (36) and comprising a dustproof filter element (48)-especially a fluted filter-on the inside, 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 (220), which pair of sealing lips (500) is connected as a single part with closing flaps (520, 1520) projecting into the interior of the dust collection box (200).
