Cut ferrous and non-ferrous metals with this Irwin Marathon bi-metal 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. Universal T-shank fits most modern jigsaws without an adapter.

• Bi-metal construction with fully hardened HSS teeth
• Precision-ground milled teeth for metal cutting
• 14 teeth per inch - general metal cutting
• 3" blade length
• Universal T-shank fits most modern jigsaws
• 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.
