Abstract (en)

[origin: US4964245A] A grinding tool body of a vibratory grinding or sanding tool has suction inlets at least in recessed areas of its working surface for sucking away the grinding dust by means of an external suction system connectable with the grinding tool body. The grinding element is in the form of a sheet of grinding linen or grinding paper coated on one side with grinding material and having a second side covering the working surface. The sheet serving as the grinding or sanding element has perforated areas coinciding with the recessed areas in the working surface. The grinding element is held in place on the working surface solely by the suction force produced by the suction system. This allows for the simple and quick replacement of worn grinding elements. The grinding material-free back or second surface of the grinding element is roughened. Preferably, for the purpose of producing such a roughening, at least two edges of the sheet are folded over, such edges being disposed opposite one another.
