ABSTRACT:
The invention relates to a circular saw blade of the sandwich-type, i.e. a blade comprising two steel discs (2, 3) on the periphery of which the cutting elements (5) of the blade are attached. In order to improve the vibration and noise damping properties of such blades an intermediate layer (4) of an energy-absorbing and solderable material is introduced between the discs and the discs are interconnected by soldering, preferably by means of a plurality of spot-like soldered joints (11), with said intermediate layer (4) serving as the solder. (FIG. 2).
