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

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.

went thru 7 layers of paint in no time at all,,the whole car took about 3 to 4 discs

This product works awesome at removing mill scale and rust to prep for welding or painting. They are very expensive so I am cautious to only use this when needed, otherwise I use cheap flap discs. Definitely worth having one or tow in your garage though.

I took a chance on this disc, but Im glad I did. Eventually, I clogged this up by accidentally grinding into something sticky, but until then it did fantastically at removing paint and mill scale. This model threads onto a threaded arbor. My angle grinder has bushings, so when I reordered these, I went with a 10 pack of the unthreaded ones. Theyre a bit cheaper.

Pricey, but well worth it for removing paint.

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.

Like the way it removes surface rust on a old 1950 car that has rust completely over entire body. Also like that you can spin it 10,000 rpm on a angle grinder. It does appear to be wearing a little fast and I am not pressing on it just laying on the panel. You don’t have to worry about particle buildup using this. Also it is threaded and spins right onto your grinder.

Did not work well to remove rust from iron but has other cleaning capabilities

I use these for mill scale removal from hot rolled steel. Hands down the best consumer product for this application. With careful use one disc will last for a very long time.

Gets the job done - and quickly !
