Scotch-Brite Clean and Strip XT Pro Disc - Rust and Paint Stripping Disc - 4.5” diam. x 5/8-11 Quick Change Thread - Extra Coarse Silicon Carbide - Pack of 1

Works really well, but unfortunately only for a couple square feet.

Remove mill scale, got about 10 minutes use. Stay with flapper wheel much faster and a way more cost effective

Works well

Great stripping disc. Expensive but if you want to speed up your stripping project then this is the product you need.

Used these to remove mill scale on sheet metal. They didn’t last as long as I thought they would.

Quickly removed mill scale on some tubing I tested it on. Very happy with this purchase and will continue to get more as needed.

I tried so many grinder wheels, wire brush wheels, cup brush wheels, etc. regular grinders would scratch the metal. Brush wheels take forever. Mill scale falls right off with this one.

While I would love it if they lasted longer, mill scale is an extremely stubborn material. These work well and probably replace at least 6 or more flapper discs that you would go through to accomplish the same job. Also, these dont damage the underlying metal. Will be keeping several in stock at all times.

These are pricey but for people like me that need a quiet, fast stripping blade this is great. For small panels like doors and fenders this works super fast and somewhat quieter than other options for stripping paint and filler. I’m in an urban area so noise levels are a big concern so I don’t mind spending a little more on a quality blade.

Lasted for about 50 seconds before worn down to nothing, yep I timed it... Went back to standard wire, and flapy disk for rust/scale removal.
