Circular saw metal blades by M.K. Morse Co.

The company has added two 10-inch metal-cutting carbide tipped circular saw blades to its Morse Metal Devil line. One 10-inch blade is designed for cutting thin steel while the other is for cutting aluminum. The thin steel Metal Devil blades have 52 teeth with 0 degree rake, creating a stronger tooth with increased metal surface area where the cut is actually being made. Aluminum cutting blades have an aggressive 80 tooth configuration with a 7 degree rake to create additional forward cutting action. Both blades work on all standard circular and miter saws, running at a maximum RPM of 5,200 for thin steel and 5,500 RPM for aluminum. The sizes range from 5 3⁄8- to 14-inch diameter.
