Abstract
Abstract A rotary saw blade is provided with annular recesses on its two side surfaces, with the recess filled with a sound-deadening material such as melted metal. The sound-deadening material is sprayed into the recesses so that the entire saw blade need not be heated to any great degree. A layer of a binding material may also be sprayed into the recesses to increase the adhesion of the layer of melted metal to the rotary saw blade.
