Abstract

A saw blade of uniform abrasive segments with undercut protection to prevent loss of segments and to extend blade life. A metal core includes a uniform peripheral contour formed as a series of spaced apart, segment mounting sections separated by radial gullet channels. A diamond cutting segment is securely bonded to each such mounting section at a bonding interface between the segment and the metal core. Adjacent the ends of each segment on opposite sides of successive gullet channels, are upstanding ears which at least register with and extend through the radial arc of the bonding interface between the segments and the metal core. Both the upstanding ears and the region beneath each segment are preferably overcoated with a wear protection material such as carbide. The overcoated region beneath each segment includes a contoured edge to assist in directing swarf away from the cutting groove.
