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

Great product. Works exceptionally well

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

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

I especially like that it sticks a bit out from the grinders protective shield, allowing to put it down horizontally. Pretty aggressive on wood though, need to touch down very gently.

I purchased this to remove mill scale. It worked great for a while, removing mill scale from curved surfaces. When I then used it on a flat piece of metal, it was by that point clogged up with mill scale residue. The only solution for mill scale is to soak the metal in acid. Muriatic acid will remove it fast, in just a few minutes. White vinegar will work in 4 to 5 hours, or overnight. Don’t buy this pad for removing mill scale. You’ll be disappointed.

Love it. Strips paint quickly without damaging the metal underneath.

Needed to remove very thick mill scale from mild steel tubing. This product was by far the fastest option I could find, it worked great.

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.

Works great while they last, but they are very expensive given how long they last. Mostly I tested them byt removing paint and/or rust from a small amount of mild steel tubing, plate and bars.

Best option for mill scale removal from steel. Also great for surface rust removal.
