What does this thing do?A. I think the description for the Milwaukee 6805 best answers your question: This fast cutting 16 gauge Shear can handle the toughest jobs, you can even cut stainless steel up to 18 gauge. Scroll cuts are a snap with the easy to hold back handle design. Easily adjusted blades make for easy work adjustment. The 6805 shear will leave a smooth, burr free edge, ready to be finished. This is a handy tool for sheet metal work, and even is used on the farm for metal fabrication. Fast, easy, clean cuts in metal are just what this tool provides.
