<p>An apparatus for cutting materials and more specifically an improved saw blade (20) includes a plurality of variable teeth (32) thereon. The variable tooth saw blade (20) cuts faster and smoother while reducing harmonic vibrations. Specifically, the teeth (32) on the saw blade are grouped into sections (80, 82, 84, 90, 94, 180, 182, 184, 186, 190, 192, 194, 196) with differing circumferential widths and differing spacing between the sections.</p> |
