"USEFUL FOR GRINDING MACHINES", characterized by being constituted by a base of elastic material, cylindrical and with its bases emptied in the form of trunks of cone with their smaller bases in contact, in whose holes they are coupled separate casings of the same form, having provided in one of them a central body reinforced in its connection to the rest by radial ribs, whose body is threaded internally, for coupling the shaft of the tool, by thread, said axis having a central area of greater diameter, so that the threading force the approach of the bushings achieving an increase in the diameter of the base and therefore solidarity between it and the emery placed on it, preventing all kinds of independent movements between both parties.
