The time-saving TURBOSHEAR Model No. TS1 inserts directly into the chuck of a standard 1200 rpm A/C or cordless drill. It’s that easy to convert your power drill to a power shear! This rugged but inexpensive accessory cuts straight and to the left and is capable of navigating tight curved patterns and squares in heavy 20-gauge (1.02 mm) galvanized steel. Blind cuts require only a 1/2”(12.7 mm) starting hole. Cutting applications include both ferrous and non-ferrous sheet metals, metal roofing/building panels, vinyl, steel mesh, ductwork, even the thick metal of furnace jackets, equipment enclosures or automotive body panels. An offset design keeps both hands away from work surface. Long-wearing hardened jaws are also replaceable. For premium performance without the premium price of a dedicated power shear, TURBOSHEAR is an easy addition to every tool box.
