Abstract
A saw blade such as a bandsaw blade, circular saw blade, or hacksaw blade has a leading tooth or teeth which cuts the workpiece and advances in a feed direction while the workpiece is being cut and a plurality of trailing teeth which cut the workpiece later than the leading tooth or teeth and serve to widen the leading cut channel. The leading tooth and the trailing teeth form one group in which a plurality of the trailing teeth are lesser in height than the leading tooth and an additional plurality of the trailing tooth are equal in height to the leading tooth. The trailing teeth are set in the right and left directions with respect to the saw blade and the leading tooth is unset with respect to the saw blade. The lateral set of the plurality of trailing teeth having a lesser height is wider than the lateral set of the plurality of trailing teeth having the same height as the leading tooth. Embodiments are disclosed in which a second group of teeth alternate with the basic group of teeth on the saw blade.
