The present invention is directed to a rotatable abrading wheel assembly useful to finish rubber articles such as tire casings. The assembly has three rotatable wheels, with a central abrading wheel disposed between a pair of lateral support wheels. Each of the three wheels is stamped and formed from sheet metal stock and includes one or more apertures to accommodate an abrading tool drive shaft. The central abrading wheel has a diameter greater than that of the lateral support wheels to thereby provide peripheral abrading portion which is comprised of a series of circumferentially spaced teeth.
