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).

Abstract: The present invention relates to a method in the production of rotatable tools, such as saw blades or similar, comprising at least two preferably metallic discs interconnected by means of glue, solder or any other binding means or adhesive wherein spacing members of a uniform overall thickness are disposed between the discs to position the discs parallel to each other and to ensure a uniform layer thickness of the binding means. Said invention also relates to a means to perform the method and to the product achieved by the method.
