ABSTRACT:
A circular saw blade having a plurality of spaced sets of teeth, each set including a first forward ripper tooth and a second rearward cleaner tooth. The top surface of each member of the pair is slanted in an opposite direction, while the ripper tooth of each pair is preferably partially chamfered on its two front edges. Each member of the pair has its two side surfaces tapering inwardly toward its respective rear surface. The cutting face of the ripper tooth is longer than the cutting face of the associated respective cleaner tooth. Each ripper tooth is preferably spaced about 15 degrees around the outer periphery of the blade from the next adjacent ripper tooth, while each associated cleaner tooth is located about 5 degrees behind the respective ripper tooth. In this manner, a single blade may be used as an all-purpose cutting blade to make clean cuts in various media without splintering.
