A method of attaching labels on rotary abrasive discs is disclosed. In a process for fabricating a rotary abrasive wheel which comprises placing grindstone material including thermosetting binder flat in a mold cavity, followed by compression molding the material and causing the moulded product to set by heating, the method includes positioning a label of material capable of withstanding the heating temperature along either surface of the grindstone material placed in the mold, prior to the compression molding step, and subsequently subjecting the label together with the grindstone material to compression in the direction of thickness thereof.
