Lenox 20155S224HE Bi-Metal Hacksaw Blade 12 in. x 1/2 in. 24 TPI

The Lenox 20155S224HE is a professional-grade bi-metal hacksaw blade built for smooth, precise cutting in medium metals. Featuring Lenox's proprietary T2™ Technology, this blade delivers up to 100% longer blade life compared to the previous generation of Lenox hacksaw blades, making it an outstanding upgrade for tradespeople and serious DIYers alike.

Constructed with a spring steel back and an M-2 high speed steel cutting edge, the blade is electron beam welded for superior bond strength. The bi-metal design allows the blade to flex under load without shattering — a critical safety advantage over solid high speed steel blades. With a tooth hardness of Rc 64–66, the Tuff Tooth™ cutting edge resists heat, shock, and wear to stay sharp longer and outperform carbon steel alternatives.
