<p>A band saw blade (10) having relatively extended pitch patterns of eight or more teeth exhibits relatively low noise and vibration during cutting operations, and uniform tooth loading characteristics. The band saw blade defines set patterns within each pitch pattern, and each set pattern is defined by an unset leading tooth (12, 18) followed by offset trailing teeth (14, 16, 20, 22, 24, 26). Each tooth within each set pattern defines a pitch ("P") between the respective tooth and the preceeding tooth in the cutting direction of the saw blade, and an accumulated pitch between the respective tooth and the preceding tooth of like set. The ratio of pitch to accumulated pitch for each tooth within each set increases from one tooth to the next, in the direction opposite the cutting direction of the saw blade.</p> |
