Cut ferrous and non-ferrous metals with this Irwin Marathon high-speed steel jigsaw blade. Fully hardened HSS teeth stand up to aluminum, sheet steel, copper, and brass that would dull or shatter a carbon blade. The 14 TPI tooth count suits general-purpose metal cutting on moderate-thickness sheet stock and light structural shapes.

• High-speed steel teeth, fully hardened for metal cutting
• Precision-ground milled teeth
• 14 teeth per inch - general metal cutting
• 3-1/4" blade length
• U-shank fits jigsaws that take U-shank (universal) blades
• 2 blades per pack

Tip: Use a slower jigsaw speed in metal than in wood and apply a light cutting oil to extend blade life - heat is what kills HSS teeth.
