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

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

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

Works great for cleaning up a cast iron block,

item was exactly as described and arrived quickly

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

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.

Great for cleaning gasket faces just wish they were cheaper

Worked great for cleaning engine block during he’d gasket replacement.

Works great better than sand paper

Works well for removing automotive finishes and metal finishing!
