The telescoping drill clamp fits drills and impact drivers large and small-including newer lithium-ion models. The recent redesign allows the tool to rotate 360-degrees and lock into position. The adjustment wrench now stores with the tool, preventing loss. The hex shank drive shaft attaches directly into the chuck of any drill or impact driver. Make your power drill a powerful slate-cutting shear! This tool is ideal for making fast straight angled or curved cuts in 4mm to 8mm natural roofing slate. Cutting the slate with finished side up produces an authentic-looking, hand-cut appearance. The padded skid plate prevents scratches to the exposed slate finish. Smooth, easy one-hand operation always leaves a free hand to steady the work when making cuts on a bench or rooftop. Cut thousands of linear feet of roofing slate quickly and easily all season long!
