A flat or center depressed abrasive grinding wheel, comprising an abrasive discoidal element which is associable, substantially coaxially, with the free end of a rotating shaft of a grinder, having at least one substantially central through hole, a first face which can be arranged, in the assembly configuration, so as to be substantially directed toward the grinder and which forms the back of the discoidal element, and a second face, which is opposite to the first face. The discoidal element comprises at least one first layer of a discoidal abrasive mix defined at the first face and at least one second layer of discoidal abrasive mix defined at least one portion of the second face. The first and second layers of abrasive mix are mutually superimposed and jointly associated. The second layer of abrasive mix has an inside diameter that is substantially larger than the diameter of the through hole.
An abrasive grinding wheel which is flat or has a depressed center, and comprises an abrasive discoidal element associable, substantially coaxially, with a free end of a rotating shaft of a grinder, said discoidal element comprising:
