Trying to find blades for Dewalt DCS571B ATOMIC 20V MAX 4-1/2" Circular Saw.Need cut-off wheel and stone blades as well as the wood blade included with the saw.Cannot find blades anywhere. Who makes them, and where can I find them?

DeWALT does not currently offer a blade for masonry and has not indicated any intention to add one. This saw appears to be designed for wood use. You can find the current blade offerings using the link below.
