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

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

Great tool for removing paint and light rust, will definitely be buying more

Great product, using it to remove Mill scale. This wheel isnt loading up as quickly as other brands.

Pricey, but well worth it for removing paint.

Nunca pensé que este tipo de discos removiera tan fácil el óxido en metales me sorprendió al utilizarlo, estoy muy satisfecho y si problemas se le adapta a cualquier amoladora de 4 Pulgadas volveré a comprar otras 2 pza.

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.

la use para limpiar unas ollas que tenían capas de grasa quemada, primero quite un poco de grasa quemada con gabon y con una carda de alambres delgados, después pase esta carda de fibra y quedaron como nuevas

Amazing for removing mill skin and rust of metal. Its 1000 times faster then a flap disk

Bought 2 of these to strip mill scale off large sheets of steel. Would work reasonably well for maybe 1-2 square feet and then got progressively less effective. Found pad was fouled by the material removed. Took steel file and removed the junk which revitalized the pad for a while but was a losing battle. Finally threw in the towel and used muratic acid to finish the job. Did find pad was very effective at removing resulting surface rust which appears once acid is washed off and panel dried. So it has a use but not as effective as the description made it sound.

These work better than anything else Ive found to remove mill scale from steel.
