Abstract
The thin kerf circular saw blade of the present invention is a high speed saw blade having a plurality of spaced teeth around its periphery. The blade contains a plurality of radial slots extending inwardly from the periphery of the blade. A combination of features including the aggressive hook angle of the teeth, a plurality of expansion slots, a shallow gullet, reinforcing shoulder, carbide cutting elements, and a thin profile provide a saw blade for cutting a thin kerf at a high cutting speed. A slick coating including friction reducing and non-stick compounds reduce resin buildup and further improve the speed of cut of the thin kerf saw blade. The improved performance of the thin kerf saw blade in comparison with conventional carbide blades is attributable to the synergistic effect of optimizing the design parameters for each of the individual structural features and combining the features according to the present invention to obtain surprisingly good results including: an increased cutting speed, reduced tip wear, and reduced energy consumption.
