Abstract
A replaceable tooth for a circular saw with a base and angled cutting surfaces defining nadirs of intersection between adjacent cutting surfaces. Inserts are provided to cover facets of the angled cutting surfaces of the replaceable tooth. Plugs of a hardened material are provided immediately below each nadir of intersection to prevent erosion of the tooth base below the intersections of the inserts.
