<p>In the case of a sawing tool for a circular power saw having two coaxial saw blades (11, 11') capable of being driven in opposite directions and rotating directly past each other, the anterior-relative to the direction of rotation-cutting edge (161, 161') of each active cutting edge (16, 16') is situated in a plane extending through the saw blade axis (18, 18') to produce, using a simple design, an axial force on each saw blade (11, 11') that counteracts the forcing apart of the saw blades (11, 11') during the cutting process, and the active cutting edges (16, 16') are sloped in the direction of the saw blade axes (18, 18') in such a fashion that they incline downward from the facing sides of the saw blades (11, 11') toward the sides of the blades facing away from each other (FIG. 5).</p> |
