<p>A bandsaw blade includes recurring groups of cutting tooth structures which are of progressively shorter height from a leading tooth structure to a trailing tooth structure. Each of the tooth structures is either: (A) a single, straight tooth, or (B) a pair of equal-height set teeth which are set to respective sides of the blade. The leading tooth structure consists of a single straight tooth having relatively large chamfers. The last tooth structure consists of a pair of non-chamfered set teeth. The next-to-last tooth structure is either a straight, chamfered tooth or a pair of chamfered, set teeth.</p> |
