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

The product performed better than listed.

I bought this disk to remove mill scale and light rust. It does do a good job cleaning both, but it wears out rather quickly. I purposely used light pressure hoping to make it last. I will not buy another one.

This takes off mill scale off fast!

Exactly what I needed to remove mill surface from plate steel when prepping to weld-no other abrasive product that I have tried compares to this-perfect! Typical 3M quality. Longevity of the disc is as yet unknown,but is a minor concern for me-I will purchase more if need be....

Ok so these are ludicrous overpriced but I decided to give them a shot after reading that they last a long time. Performance on steel is top notch. Tore right through light rust and mill scale almost effortlessly, leaving a surface that is ready to weld. Durability- I got maybe 30 minutes out of one pad. That doesnt seem THAT bad until you consider that these are $15 a pop. Im sold on the concept but not this particular product at this price point. Going to try some cheaper options under $10.

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

The only pads I’ve tried that thoroughly clean metal without marring the surface like flapper disks do. And they don’t seem to clog up as much as other brands. Pricey but worth it.

Works great and lasts longer

Removes paint and mill scale without marring the underlying steel better than anything Ive ever used. Durable. Worth the price for a quality product.

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.
