Abstract: The invention describes a drill plate with a clamping attachment in a rotatably driven base body, which on one of its end faces forms a centering groove that is open towards the top. A clamping slot extending into the material of the base body is arranged at the bottom of the centering groove. The centering groove is bounded by at least two opposing mounting jaws, with at least two diametrically opposing stop faces arranged in the region of the clamping jaws for providing centering contact with the drill plate. The clamping attachment is formed by a mounting screw which clamps the drill plate in the centering groove (2.3).
