The wheel has a circular ring-section including linear front and rear edges (15, 16) lead from an inner edge (13) to an outer edge (14) based on drive-rotational direction (21). The inner and outer edges limit a part of another outer edge (26) of a grinding lamella covering, and the front edge extends from a grinding lamella (6) in to the drive-rotational direction. The rear edge is opened and limits a grinding-insert surface (11), and is arranged in a layer parallel to another layer and perpendicular to central axis (4). |
