ABSTRACT:
A circular saw blade has block-like tooth tip inserts of hard metal, secured at circumferentially spaced intervals to the peripheral portion of a disc-like blade body having opposite flat side surfaces. The gullet in front of each insert, conventionally present in such a blade, is spanned in the circumferential direction, at least to a substantial extent, by a fixed thin wall, which can comprise a reduced thickness portion of the blade body, so that each gullet is thus defined by a sidewardly and radially outwardly opening cavity in a side surface of the blade, and the blade has a near-circular periphery. At the circumferentially rearward and radially inward portions of each cavity its edges are substantially bevelled to facilitate flow of cuttings out of the cavity.
