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

Best option for mill scale removal from steel. Also great for surface rust removal.

In the title it shows 10 per case, you only get one

Decent at removing hot rolled millscale when new but gets very hard to use and requires a lot of pressure once it starts to wear, I just used an Aluminum Oxide grinding wheel to get the millscale off and a flap disc to smooth it out. Faster and cheaper even though you’re going over it twice. These weren’t worth the money for me. Three stars since they did work well when they worked and left a beautiful finish.

Broke down didnt last but 5 min of use..

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.

Money well spent AND reusable

I used this to remove *heavy* mill scale from all the surfaces of a 10” piece of W8x40 I-beam. It took probably 65% of the disc to do it but it did an outstanding job. 3M states it’s only for light mill scale; mill scale doesn’t come much heavier than what I used it on. And no danger of cutting into the good steel or dishing it.

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.
