Make your power drill a powerful slate-cutting shear. The Malco Turboshear Model TSNS1 quickly inserts into the chuck of most corded or cordless electric drills. This versatile and "portable" TurboShear requires less force than other slate-cutting methods. An operating speed of 1400 to 2000 RPM ensures optimal performance and control for making fast straight, angled or curved cuts in 4mm to 8mm natural roofing slate. Cutting slate with finished side up produces an authentic-looking, hand-cut appearance. A padded skid plate prevents scratches to the exposed slate finish. A streamlined, lightweight aluminum shear head and telescoping drill clamp make this compact attachment adjustable for both length and width of the drill housing to go where the work is. 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. You can even rotate the tool's skid plate to maximize acceptable cutting life. And the long-wearing blade and skid plate are also easily replaced on the job.
