Make your drill a shingle shear. TurboShear Model TSS1 is specialized for cutting all types of asphalt shingles. This one-hand operation accessory quickly inserts into the chuck of most cordless or corded power drills to go anywhere the work is. Make fast, clean, straight trim cuts along a roof valley, or make square cuts and circles in shingles with equal precision and ease to fit around utility outlets. A wide jaw opening with a beveled lead-in tip accommodates multiple shingle layers and a lateral blade adjustment capability makes this shear easily maneuverable in any life-rated shingle or thickness. A wide lower blade offers exceptional operator control. Heat-treated carbon steel blades with solid carbide inserts assure long cutting life. Replacement blades are also available and are easily installed at the job site.
