Milwaukee 48-00-4188 9" Ice Hardened Sawzall Blades, 18 Tpi (5-Pk)

Features and Benefits:

• Ice Hardened™ for up to 50% longer life
• A unique combination of relief angles forms a radius on the back of the tooth that reduces stress build-up during cutting and substantially extends blade life
• Precision forming process creates sharper teeth for fast cutting
• Matrix II bi-metal teeth for greater durability
• Optimal for cutting metal 1/8-5/16 in. thick

Ice Hardened™ blades are cryogenically treated to minimize soft metal (austenite) and create more hard metal (martensite). The result is a metal cutting blade that is more consistently hard through-out, for up to 50% longer life than standard blades.
