12" Metal Demolition Blades, Double Duty, 18 TPI, 5 Pack

Milwaukee 48-00-5789 – 12" SAWZALL® Metal Demolition Blades with 18 TPI (5-Pack)

The Milwaukee 48-00-5789 SAWZALL® blade is a 12" demolition-grade reciprocating saw blade designed for fast, controlled cutting in thick and thin metal materials. Manufactured with bi-metal construction and 18 TPI, this blade is optimized for applications such as conduit, angle iron, rebar, threaded rod, and structural steel demolition.

Featuring Milwaukee’s Double Duty Upgrade™, the blades incorporate a reinforced tooth geometry for extended blade life and increased cutting speed. The Tough Neck™ design strengthens the tang to reduce risk of breakage under high-stress use, while the Grid Iron™ stamped honeycomb body increases rigidity and minimizes flex during aggressive cuts.
