Not sure if any of you have heard of this but i use a 4" twin cut saw. it's resembles a 4" angle grinder but it is not the same and can not be used as a twin cut saw. one blade turns one direction the other turns the other, it uses carbide tip blades and they last a very long time. I first was a bit skeptical but decided to make the plunge and now i am so glade I did. After getting it I thought i would put this to a test on stainless steel about an 1/8" thick, wow what a job it did went through it like butter. I am still using the same blades and it has been a good ten years now. ( not in business just DIY stuff) It makes very small chips so i wear gloves and face shield and it does make a lot of noise and some sparking so be careful on where you do your cutting. It cuts metal roofing fast and almost no burs left on the metal. I have learned through trial an era that if you clamp a board to the metal roofing that it does not flex and makes it easier to make a clean straight cut.
