Make smooth, precise cuts in metal with this Irwin Marathon high-speed steel jigsaw blade. The fully hardened HSS construction handles aluminum, sheet steel, and other metals that would destroy carbon blades. The 20 TPI tooth count delivers finer cuts than the 14 TPI variant, ideal for thinner metals where a smooth edge finish matters.
