I needed to cut up an old water heater tank so I could dispose of it in my trash. This disc cut thru the outer skin with ease, then I had to cut thru the inner tank which was about an 1/8th inch thick. Of course that part went slower than the outer skin, but it still cut pretty quickly and didn't leave a lot of burrs.It took a toll on the cutting disc to cut all that. But it's still usable for future cutting and grinding. And I still have 4 used discs left.All in all, I'm happy with the product and the price.
