<p>A rotary saw blade (20) for cutting a metal workpiece. The blade includes a generally circular main body plate (22) having an opening (24) at the center of the plate and a plurality of raised tooth support members (26) disposed about the periphery of the plate. Each of the support members has a tooth attachment portion (27) generally facing the direction of rotation of the blade and a peripheral guide member (32) extending away from the tooth attachment portion. A plurality of cutting teeth (28) are each mounted on one of the tooth attachment portions. Each of the tooth support members define gullets (60) between each of the guide members and extending generally radially inwardly toward the center of the blade. The gullets are further defined by a throat area (70) and a rounded area (62), wherein the throat area defines a gap width (10) between a peripheral guide member and a tooth.</p> |
