A circular saw blade for mounting on a powered saw arbor with the blade having saw shoulders spaced thereabout defining open gullet areas. Block shaped teeth of tungsten carbide, or the like, have a bevelled front face at one end of the tooth providing an accentuated rake angle for cutting efficiency. A tooth major axis is disposed substantially normal to a saw blade radius. The saw blade shoulder has an outer edge tangential to its circular path.

A circular saw blade comprising, a saw blade having shoulder portions spaced about the saw perimeter defining open gullet areas therebetween, and saw teeth of block shape one each in place on one of said shoulder portions, said teeth each having a major axis substantially normal to an intersecting saw blade radius whereby load forces are imparted along vectors generally orientated lengthwise of each tooth, said teeth each having a beveled front face defining an included angle of between forty and fifty degrees with a tooth intersecting saw blade radius.
