Circular saw blade, has screw holes with opening angle smaller than ninety degrees and extended apart from large head diameter area of retaining screws in such a manner that distance to screw head is given without internal stress
Circular saw blade, has screw holes with opening angle smaller than ninety degrees and extended apart from large head diameter area of retaining screws in such a manner that distance to screw head is given without internal stress
The blade has an auxiliary ring (2) concentrically connected with a saw blade body (1) in a connecting surface by welding, soldering and gluing. Screw holes (7) are formed in such a manner that compressive forces of retaining screws are transferred over an external area of heads of the retaining screws. The screw holes has an opening angle smaller than 90 degrees and are extended apart from a large head diameter area of the retaining screws in such a manner that a distance to a screw head is given without internal stress.
