5Pcs 4.5" x 7/8" Nylon Fiber Buffing Wheel Scouring pad Flap Polishing Disc for Angle Grinder (Grit 800)

works very well for buffing copper

I used these to polish aluminum grill to a bright finish on my son's old Ford. These last a long time and are easy to use.

Bought this to clean up around the house, specifically my glass stove top. Removes grime and gunk immediately with no ease paired with an angle grinder, and no visible marring left behind. Need to be cautious working around edges as parts of the wheel will snag and come off, making the disc no longer usable.

Kinda polishes. They don't last long and its easy to put heat marks into aluminum as you are polishing. Then they are not strong enough to remove the heat marks.

This items perfectly onto my angle grinder. I finally realized is 800 grit in a wonderful usable sander of sorts. If I need the sand again I definitely will purchase more of these.

As described

I liked these on flat, open, clean metal panels to scuff the surface. Don't run them into an edge because they will disintegrate.

Well, they worked. My diamond plate running boards were neglected for years. That said, these things sure didn't last long. About 3-4 minutes and they just wore right out. I managed to clean up both running boards for a reg cab truck, so I suppose they did their job but they sure are made cheap. I wouldn't buy them again. I'd rather have something that lasts and pay more instead. Just buy these if you have a small project and don't think you'll need to maintain aluminum again and you'll probably be happy enough.
