DEWALT DWASHRIR metal cutting attachment. It can cut materials up to 18 gauge: not only sheet metal, but also corrugated metal, ductwork, roofing shingles, steel mesh, vinyl siding, it can even handle wire, plastic, cardboard and rubber.

The attachment is compatible with almost all 18-20 volt drills and impact screwdrivers, regardless of brand. It has a standard 1/4-inch hex shank that fits most tools. Think of how many tools this attachment can replace: metal shears, a vinyl cutting knife, a roofing cutting tool.
