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

It worked great for removing mill scale they just dont last as you would think for tha price. I gave it a 4star ratings because of the price and how long they last

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.

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

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.

Money well spent AND reusable

Gets the job done - and quickly !

These disks are very good at removing the paint and leaving the metal below in good condition

It worked great but didnt last as long as I would have thought.

I removed mill scale from a price of 1/2” plate. The disks work best if you use light pressure and take your time. If you are pushing really hard they break down quicker and the amount of mill scale you remove per disk greatly decreases. Working from the edges of the mill scale also works best, rather than starting on top of a solid mill scale area.

The product performed better than listed.
