<p>A circular saw, wherein the side cutting blade of a tip (20) fixed to the outer periphery of a circular saw main body (11) is provided with inflection points K at the parts from which the tip is projected most sidewardly, and the set angle at the inflection points of the side cutting blade on the outer peripheral side is negative of -1° or larger and less than 0° and the set angle at the inflection points of the side cutting blade on the inner peripheral side is positive of exceeding 0° and less than 1°, whereby a cutting surface excellent in surface roughness more than before can be obtained in cutting soft materials such as wood using the circular saw.</p> |
