ABSTRACT:
An abrading element for mass finishing of workpieces such as vibratory finishing comprises an elongated metallic rod of generally circular or other curvilinear cross section with serrations extending over substantially its entire periphery along its elongated axis. The serrations provide cutting edges along their outer surfaces and recesses therebetween. The metal of the rod is hardened at least in the portion adjacent the surface to provide hardened cutting edges and a wear resistant surface. The abrading elements are conveniently formed by severing rod or wire stock in the desired length and rolling or otherwise forming the desired serrations therein, after which the abrading elements may be hardened.
