ABSTRACT:
A rotary saw blade having a substantially circular disc with opposed parallel faces and a centrally located opening through the disc to receive a drive member to rotate the disc. The outer edge of the disc has a plurality of equally spaced depth gauge protuberances located around its periphery and a pair of spaced holes extend through the disc adjacent to the outer edge at each protuberance. A saw tooth is attached to the disc on one face at alternate pairs of holes and a saw tooth is attached to the disc on the opposite face at the remaining pairs of holes. Each saw tooth has a cutting edge and a depth gauge and the depth gauge on each saw tooth has a shape and a size which are complementary with a depth gauge protuberance on the outer edge of the disc, and a face of the depth gauge on each saw tooth is in contact with a face of a protuberance on the outer edge of the disc. Each saw tooth is attached to the disc by rivets.
