Cut thin metal cleanly with this Irwin Marathon high-speed steel jigsaw blade. Fully hardened HSS teeth handle aluminum, sheet steel, copper, and brass, and the 20 TPI tooth count delivers a finer finish than the 14 TPI blade - the right choice for thinner sheet stock where edge quality matters.

• High-speed steel teeth, fully hardened for metal cutting
• Precision-ground milled teeth
• 20 teeth per inch - fine metal cutting
• 3" blade length
• T-shank fits most modern jigsaws without an adapter
• 2 blades per pack

Tip: A standard rule of thumb in metal cutting is to keep at least three teeth in contact with the material at all times - step up in TPI as the stock gets thinner.
