ABSTRACT:
A band saw blade comprising a plurality of teeth, wherein each tooth comprises a tip; a rake face formed on one side of the tip; a primary clearance surface formed on an opposite side of the tip relative to the rake face; a secondary clearance surface formed on an opposite side of the primary clearance surface relative to the tip; and a gullet located on an opposite side of the rake face relative to the tip and defining a depth (D) between a base surface of the gullet and the tip. Each tooth further defines a first gullet radius (R1) located between the gullet and the secondary clearance surface; a second gullet radius (R2) extending between a base surface of the gullet and the rake face; and a pitch (P) between the respective tooth and a preceding tooth. In each tooth, R2>D>RQ, and D/P is between about 25% and 35%.
