SAWING TOOL FOR A CIRCULAR HANDSAW MACHINE WITH TWO COAXIAL SAWING BLADES WHICH CAN BE DRIVEN IN OPPOSITE DIRECTIONS AND ROTATE PAST EACH OTHER

摘要

The present invention relates to a kind of cutting tools for circular handsaw machine, opposite direction that tool can be driven in the reverse direction each other there are two coaxial saw blade (11,12) simultaneously has rotated priority, and the blade, which is respectively provided with external tooth (13,14), indicates main cutter. The task of the present invention is the quality for improving cutting, even if when the problem of tool wear becomes increasingly and avoids and tooth (13,14), when saw blade (11,12) is not in a manner of precise plane. For this reason,Other cutter (10) is disposed in two saw blades (11,12) so that material roll (171) optionally remaining in saw blade (11,12) and can work after sawing. The web, which is rotationally fixed to one of saw blade (11,12), to be had and main cutter axial overlap.
