3M 048011-18730 3M-18730 Roloc Bristle Disc Grade-50, Size-2, Green

I used this to strip some 30-year-old, very had gasket material off of a piece of aluminum. I chucked it up in my drill press and at first the RPM was around 1200 and it was painfully slow. Kicked it up to 3100 RPM and it was GREAT! Care must be taken with the Green version on aluminum so as to not damage it, I believe the White grit is preferred for aluminum so I tried this on an old piece part. Ill use the white for critical parts, especially if I ever use it at the rated RPM.

This is a monster on a die grinder. Very fast and thorough cleaning of wheel huba

Great for cleaning gasket faces just wish they were cheaper

Along with a carbide scraper, quick for preparing previously painted metal railings and some ornate areas like vines/leaves in flaky ironwork. Time saver, left great surface for priming.

Works great for cleaning up a cast iron block,

Works great.

I have used these for removing rust from metal and paint from wood without the usual dusty mess of sandblasting or sand paper

This is fantastic for cleaning old head gasket material off aluminum or cast iron heads and blocks. I’m sure it works great for many other things but that’s all I use these for. Spending 10 hours with a razor blade is now a thing of the past.

I use this, a razor blade and sand paper for engine surfaces, also polishes cases, parts .etc. Head gaskets .etc a must have along with a fast drill or air spinny tool with adapter for this wheel. Just dont spin too fast, you have to adjust air pressure to get the perfect revolution of spin.

Great for removing silicone and old gasket material from engine components.
