Kind of a love hate relationship with sheetmetal shears. When they work they are great. But when the blades get funky an absolute nightmare. My milwaukee was crap from the get go i had to modify the head to stay on the damn thing. Too much abuse its all wore out and cracked on the buisness end now i use a porter cable air powered one. It didnt work worth a damn from the start I had to rework the blades a bit. Now its acceptable. But man there has to be a better way. Plazma cutter? I think so
