ABSTRACT:
An improved circular saw blade is rotatable in a guard casing having tree receiving vertically aligned openings in its upper and lower plates. The blade has a peripheral surface formed in part by a series of replaceable circumferentially spaced teeth with transverse cutting edges positioned to rotate about a predetermined first radius. The blade also has a series of circumferentially spaced, generally radially projecting backer tooth mounts for receiving the rear surfaces of the teeth. The mounts have sloped peripheral surfaces lying radially inside the first radius of rotation and have rear surfaces generally parallel to the mount front surfaces. The saw further has generally tangentially projecting finger-like guides in a guide region spaced circumferentially forwardly from each tooth to provide a radially extending chip passing slot between each tooth and guide and the guides have peripheral surfaces positioned to rotate radially inside the first arc of rotation about a second arc of rotation. Rearwardly and outwardly extending trailing surfaces extending substantially perpendicularly from the rear surfaces of the mounts lead from the tooth mounts to the guide peripheral surfaces to form the peripheral surfaces of the saw between the tooth mounts and guides. A series of loop shaped openings join to the chip passing slots and have marginal radially angular chip deflecting walls extending at an angle in a forward direction. Fasteners extend chordally through the mounts from the rear of the mounts into the teeth to releasably secure them to the mounts.
