Diablo's aluminum cutting saw blades produce fast, accurate cuts in aluminum and other non-ferrous metals without bogging down your cordless saw's battery. This 20mm arbor saw blade includes three additional bushings that allow your blade to also 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 maximum life, performance and durability in aluminum 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.
