SAWING TOOL FOR A MANUAL CIRCULAR SAWING MACHINE WITH COAXIAL SAW BLADES THAT CAN BE DRIVEN IN OPPOSITE DIRECTION

摘要

The invention relates to a sawing tool for a manual circular sawing machine comprising two coaxial saw blades (11, 11') that can be driven in opposite direction and that can rotate immediately past each other. The invention aims at enabling a constructionally simple generation of an axial force in each of the saw blades (11, 11'), said force preventing the saw blades (11, 11') from pushing apart during the cutting process. The front cutting edge (161, 161') of each major cutting edge (16, 16') rotating in the direction of rotation lies on a plane extending through the axis of the saw blades (18, 18'). The major cutting edges (16, 16') are slanted in the direction of the axis of the saw blades (18, 81') in such a manner that they tilt from the sides of the blades of the saw blades (11, 11') that face each other to the sides of the blades that are opposite each other.
