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

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

Money well spent AND reusable

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

this thing remove mill scale like a eraser ! and does not clog up / pile up the scale to the disk like the flap wheels does. it remove the scale and gives a well polished shine to the surface. Must have in the shop if you are doing metal work.. it is little pricy though.
