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

The gold standard all the cheaper alternatives are not as durable or function as well

These little grinding disks are very good about cleaning calcium off my pool and leaving the tile nicely polished.

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.

Picture is misleading. You get only the green bristle disc..

Used it to clean gasket surface from an engine. Reviews here say its good, Youtube channels recommend it, so I gave it a try. Cleaned everything off, metal looked and felt smooth to the touch, rebuilt the engine with a compression of 5-10 psi. Thats it. Engine is toast. Everything is torqued to spec, head gasket and head bolts are new. This isnt even my first rebuild, I thought Id save some time using this method rather than the method of soaking in solvent, waiting, repeat process.

great product!

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

Used this today on my 40 + year old water pump gasket. Cleaned it right up.

Another great 3M product. It worked very well in cleaning the engine block for a head gaskets replacement

I recently tried a knock off from here on Amazon and the material. I don’t believe was even the same base material and it certainly didn’t work the same so far I haven’t found anything that truly compares to the three in brand green roloc emery discs.
