Abstract
A saw blade such as a bandsaw blade, circular saw blade, or backsaw blade has a pair of leading teeth which cut the workpiece and advance in a feed direction while the workpiece is being cut and a plurality of trailing teeth which cut the workpiece later than the leading teeth and serve to widen the leading cut channel. The leading teeth and the trailing teeth form one basic group in which the heights of the trailing teeth from a basic position on the saw blade are equal to or smaller than the height of the leading teeth. The trailing teeth are set in the right and left directions with respect to the saw blade and the leading teeth are slightly set with respect to the saw blade.
