ABSTRACT:
A metal cutting band saw blade has a plurality of cutting teeth defining a cutting direction, and a repeating tooth pattern of between 3 and 7 teeth. Each tooth defines a laterally-extending upper surface having a width and a height with respect to the back edge of the blade, and side surfaces extending laterally and downwardly on opposite sides of the upper surface relative to each other at acute angles relative to the upper surface. The teeth located rearwardly of the first tooth with respect to the cutting direction of the saw blade define progressively lower heights and progressively smaller acute angles of the side surfaces, and the widths of the upper surfaces of these teeth are greater than the width of the upper surface of the respective first tooth.
