摘要

The blade e.g. circular saw blade (1), has a cutter graded in teeth depth, and longer and shorter teeth (2.1, 2.2) comprising a plate-like cutting edge (3) with graded cutting width. Radial outer regions (5) of the cutter are narrower than an inner rear region of the cutter. The rear region on both sides is broader than the outer region. The outer and inner regions are parallel and symmetrical to a central plane of saw blade thickness at equal setting angles of side edges. One tooth exhibits smaller height than another tooth, and the teeth exhibits equal breadths.
