Abstract
An apparatus for cutting materials and more specifically an improved saw blade includes a plurality of variable teeth thereon. The variable tooth saw blade cuts faster and smoother while reducing harmonic vibrations. Specifically, the teeth on the saw blade are grouped into sections with differing circumferential widths and differing spacing between the sections.
Claims25
A saw blade comprising:
- a flat circular disc having a peripheral outer edge;
- a center hole formed in the disc;
- a plurality of circumferentially spaced teeth projecting radially outwardly from the peripheral outer edge;
- a cutting edge on each of the teeth;
- a first group of the cutting edges;
- a first circumferential width defined between each adjacent pair of the cutting edges in the first group;
- a second group of the cutting edges;
- a second circumferential width defined between each adjacent pair of the cutting edges in the second group and differing from the first circumferential width;
- a third group of the cutting edges;
- a third circumferential width defined between each adjacent pair of the cutting edges in the third group and differing from the first and second circumferential widths;
- a fourth group of the cutting edges;
- and
- a fourth circumferential width defined between each adjacent pair of the cutting edges in the fourth group and differing from the first, second and third circumferential widths.
