Mounting of a circularly fitted insert tooth of a circular, saw. An inserted tooth having a circular mounting surface is mounted on a blade body and into a round-bottomed notch whose opposite edges are parallel. The tooth is locked in the notch by means of a rivet which is positioned in a juncture between the removable tooth and the blade body along a straight portion of the edge of the notch. Such locking facilitates a strong design for said tooth and even a loose tooth can be re-tightened in position by means of the flattening pressure of said rivet.
