Abstract
A grinding body for working surfaces, in particular wood surfaces, has a support part carrying grinding material. The support part is movable relative to the working surface and has suction ducts ending on a working side for vacuuming off the grinding dust by means of an external suction system. For improving the suction performance, the inlets of the suction ducts are arranged in first surface areas of the working side. These areas are recessed inwardly compared with grinding second surface areas of the working side. Thus, each first surface area has the inlet of the suction ducts at the bottom of a recess in the working side.
