Diablo's Steel Demon metal cutting saw blades produce fast, accurate cuts in mild steels without bogging down your cordless saw's battery. This 20mm arbor saw blade includes three additional bushings that also allow your blade to fit on 1/2 in., 5/8 in. or 10mm arbor saws. These blades feature Diablo made TiCo hi-density carbide engineered exclusively to deliver up to 40 times longer life when compared to one standard bonded abrasive disc in mild steel applications. Designed with a Triple Chip Grind (TCG), the blade's carbide teeth produce clean, burr-free finishes, virtually eliminating any type of rework. The thin kerf body minimizes material removal and requires less cutting power, delivering fast, clean cuts.
