Title: Dewalt Masonry Board Jig Saw Blades.
Review: I bought these blades to do cut outs on fiber cement board siding. They only cut through about 20 inches of material before over heating and bending. They didn't last long at all. I can't say how well they will work for other material but do not buy them for cutting fiber cement siding.
