<p>A wood cutting band saw blade (10) includes a cutting edge (14) and a back edge (16), wherein the cutting edge is defined by a plurality of teeth (17, 17') spaced relative to each other. The plurality of teeth include a plurali ty of set teeth each having a tip (20, 20'), each defining a bend plane (18), a nd each including a shelf (30, 30') located at least partially between the tip and the bend plane for reducing saw dust passing to the kerf and accumulatin g on the band saw blade. Each of the set teeth may define a relief surface (244', 244'') and a cutting surface (224', 224'') where the relief surface extends from one side of the tip in a direction opposite that of the movemen t of the band saw blade and the cutting surface extends from another side of t he tip. The shelf includes a shelf surface (34, 34') extending from the cutting surface (24, 24') and may terminate in a shelf tip (36, 36').</p> |
