I saw a fabrication video and glimpsed this product from 3M. I got one from Amazon and tried it out today.
This is the freaking bomb. It took off mill scale and rust about 90% faster than with a flap wheel - it blew my mind. Great finish, no real metal removal.
We'll see how long it lasts. It's not cheap at $22, but good quality flap wheels are nearly the same. But as a time saver - wow am I impressed.
Caveats:
I need to get a respirator - I should have one already but the barn I work in is, shall we say, well ventilated. This throws a lot of dust.
Do NOT get near sharp edges in tight corners. This thing will grab and launch your grinder out of your hands. First time for me in 30 years.
