This lightweight, variable-speed pistol-grip shear cuts 14 ga C.R. mild steel and most grades of stainless to 16 ga and aluminum to 0.125. Double-insulated, the 5 A KD-440 cuts at over 150 in per minute, leaving a clean, flat sheet, ready to fabricate. Distortions are absorbed in an easily disposed of waste curl, leaving the sheet cool and free of burn, chips and burrs. The cutting blades are finest high-speed steel, which you can easily replace.
