<p>In the manufacture of saw blades or saw blanks (1), radial slots terminating in a plugged circular stress hole are well known. The manufacture of such blades or blanks (1) requires multiple machining steps and separate plug elements (6). This invention provides circular saw blades or blanks (1) including a radial stress relief slot (12) in which radial stress of the slot is dissipated in a "self plugged" slot base having a curvilinear configuration (11, 13, 14) extending from the slot (12). The slot (12) does not depend upon the introduction of foreign media (6) for noise suppressing characteristics. A method of making the same is also described.</p> |
