摘要：The method involves drilling a borehole (7) in a constructional component (6)with a percussively-rotationally driven hollow drill (12). The produced drillings and

drilling dust are aspirated with a vacuum source (26) e.g. vacuum cleaner, between anouter side of the hollow drill and a borehole wall during drilling of the borehole. Theborehole is filled with a self-hardenable mortar immediately after formation of thesuction-cleaned borehole. A fastening element e.g. threaded rod, is inserted into theself-hardenable mortar. An independent claim is also included for a method for forming acleaned borehole in a constructional component for anchoring a fastening element in aconstructional component with a self-hardenable mortar.
