<p>Disclosed is a tooth form for cutting tools such as band saw blades, circular saws, hacksaws and other saw type products. This tooth form yields benefits such as low vibration, straight cutting, high feed rates and smoothness of cut. It is characterized by having at least two un-set teeth (1, 2) arranged with at least two set teeth (3, 4). The un-set teeth (1, 2) cut a stabilizing groove in the work piece whereas the set teeth (3, 4) widen the kerf to allow passage of the blade. The tooth pitch, tooth height, and geometry of the teeth can be either uniform or variable. The preferred embodiment has two un-set teeth (1, 2) and two set teeth (3, 4) such that five chips are formed before the pattern repeats.</p> |
