Abstract
A saw blade is provided including a circular metal disc including a circular metal disc including a central aperture and a plurality of teeth spaced around a periphery of the circular metal disc. A first plurality of fully enclosed body slots are generally equally spaced from a center of the circular metal disc by a first distance and a second plurality of fully enclosed body slots are each disposed directly radially outward from a respective one of the first plurality of body slots. The second plurality of slots are generally equally spaced from the center of the circular metal disc by a second distance greater than the first distance. The saw blade design provides a blade with no modal frequencies in the operating frequency range.
