Abstract

The grindstone has a receiving region (2), a central grinding region (1) with through apertures (3) and cutting bodies (4) at different spacings. The long side (5) of each cutting body facing the central receiving region is at and angle of 35-55 degrees to a radius (R) originating in the central receiving region, at a tangent to an edge (K) formed from the long side and the wide side (6) of the cutting body facing away from the entral receiving region.
