Abstract: A grinding disc for a grinding device, with a fastening interface formed for rotationally fixed fastening to a driven member of the grinding device such that the grinding disc, limited by a peripheral disc rim surface, can be driven into a grinding movement. The grinding disc has a fastening surface on a working side, to which fastening surface a grinding means provided with an abrasion layer can be or is detachably fastened via fastening means. The grinding disc has dust extraction openings arranged on the fastening surface and air intake openings arranged on the disc rim surface, which are connected respectively to dust outlet openings arranged on the device side of the grinding disc via an extraction channel system running in the grinding disc, with the result that, during grinding, the resulting grinding dust can be removed by means of a dust extraction device coupled to the grinding device.
