Here's a tool that loves a good challenge. It cuts through any sawable material (wood, nail-embedded wood, steel, cast iron, aluminum, brass, drywall, composition materials, hard rubber, cement, brick, plaster, and fiberglass) with a 3/4-inch stroke. It's powered by a 6 amp variable-speed motor, and features 0 to 2,400 spm. The heavy-duty steel Quik-Lok blade clamp gives you fast, easy blade changes without the need for a hex key. It also features an adjustable pivot shoe, direct access to the blade clamp screw, direct access to pivot shoe adjusting screws, and a cord that is positioned for easier plunge cutting. All ball and roller bearings. Your Sawzall comes with a steel case and two-blade pack.
