Make extra-fine cuts in thin sheet metal, tubing, and precision metalwork with this Irwin Marathon high-speed steel jigsaw blade. Fully hardened HSS construction handles ferrous and non-ferrous metals, and the 36 TPI tooth count produces the smoothest edge finish in the U-shank lineup - the right blade for thin gauge sheet, conduit, and small-diameter tubing where a coarser blade would tear the work.

• High-speed steel (HSS) for metal cutting durability
• Precision-ground milled teeth - fully hardened
• 36 teeth per inch - extra-fine metal cutting
• 3-1/4" blade length
• U-shank fits legacy jigsaw models (pre-T-shank)
• 2 blades per pack

Tip: 36 TPI is for thin-gauge work and tubing - on stock thinner than about 22 gauge, run the jigsaw at low speed with light pressure to avoid stripping the fine teeth.
