The Milwaukee 12 in. Sawzall Wrecker Blade is designed for multi-material demolition cutting. The aggressive tooth and 6 in. blade design provides the capability to cut nail embedded wood, plastics and a variety of metals with increased speed from an optimized, sharper cutting edge on each tooth. Designed with 25% more high-speed steel and a thicker, more rigid blade body, these blades deliver users increased life and durability. A complete, unset raker tooth on the blade tip creates easier, faster plunging by minimizing walking and bouncing. These reciprocating saw blades have 7/11 TPI.
