These pipe cutters worked great! I had to replace a portion of the exhaust under my '99 Corvette, which is all stainless steel, by the way. Though these are called out as being Not For Stainless, they cut through the Vette exhaust without an issue. I used a good lubricant (Marvel Mystery Oil, love that stuff!), and cut through both pipes in a couple minutes each, without any damage to the cutting wheels.
I used this cutter on 3 inch stainless steel exhaust pipes, just two cuts in tight spaces. Worked perfect! I oiled the hinges and cutting wheels before using and each cut took maybe 10 minutes. Clean cuts, a little deburring was needed. No damage to the tool whatsoever. Great little helper for that price!
It works well, my only issue is just that as expected, it's somewhat awkward to use in tight spaces. The blades have held up pretty well considering the amount of use it gets, and the build quality is acceptable. The only issue I have is some of the adjustment lengths are very awkward and extremely tight while some are far too loose.
The metal that comprises the jaw connections that attaches to the cutting chain is too thin and deformed on use. I had to use pliers and a screwdriver to pry the cutting chain off. If not for that it would be a good tool.
