Designed to cut ferrous metals, rebar, galvanized steel, steel studs, cast iron and nail-embedded wood. The exclusive steel-cutting grade of C-6 Tungsten Carbide extends performance of the blade in dry cutting applications. Our cores are steel alloy Teflon with specially shaped expansion slots to minimize heat buildup and reduce warping. A preferred alternative to abrasive cutting wheels due to cleaner, faster, burr-free cuts that leave the work piece cool to the touch. NOT RECOMMENDED FOR CUTTING METALS THICKER THEN 1/4".
