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

can not be wrong when cleaning aluminum service , still make sure use light pressure to do so.

I got the green one which is for iron surface finishing or body work, my words as well as other Techs. White is finer grit (under 200 though) and better for aluminum surfaces. Let me caution you that no matter how safe Techs like myself want to say these are, they sort of arent in some situations. Polishing a blocks cylinder head surface and getting some down debris that you may not be able to see down in the engine...not ok. Some people line things with oil and paper or q tips as I do to plug passages and holes. etc. Water jackets not a huge deal, if you are going to flush it and use an compressed air to clean away debris...yet not perfectly clean inside engine. Many techs will NOT use these on blocks surface. I do. You sort of have to decide for yourself the risk and proper preparation to actually use it on a block. Other places I dont even prep I just buzz (lightly) off the material and enjoy the long lasting bristle disk for about 3 heads or various jobs. I can use the worn down flat part in the end later for rust on the frame or body. So I feel I get good use here, but it is costly. definitely better than 3m roloc fiber disk. Longer life, less hassle.

Works well for removing automotive finishes and metal finishing!

This tool is a good one to have laying around when you need it. I will buy it again.

These pads are fantastic for cleaning carbon buildup from aluminum and stainless car parts. Used the white pad to clean up mating surfaces of aluminum engine heads and block. Makes for a nice, clean surface with no scuffing or gouging. A must have for any mechanics shop.

Returning; needs some special adapter, not included, not clear on what would fit

Very pleased good price

Did not work at all for sanding detail on a table I was refurbishing... not sure what a good application would be.

Works well, but doesnt last very long and is very expensive. The bristles really get into cavities and ridges. I bought one to try it out and it lasted about 15 minutes of use.

No connector.
