NuoDunco 10Pcs 4-1/2" Nylon Fiber Flap Disc Polishing Wheel, 4.5" x 7/8" Abrasive Grinding Discs, 600 Grit Buffing Wheel Scouring Pad for Brush Finishing

Used this to polish a cast iron pan. Worked well and was durable to compete the job without needing to change the pad. Removed all rust and roughness with ease.

I was able to pretty much polish aluminum using these. With the 600 grit pad it does leave some residue if you push too hard and get it too hot the glue that holds it together melts. I was able to get the residue off by going down a grit level. The lowest grit never left a residue

These abrasive disks turned out to be the best for prepping antique exterior windows sills (my 1892 home has more than 30!) for refinishing. These sills had lots of water damage, just painted over again and again with low quality paints by previous owners. These disks were easy to use with a grinder and left a very repairable surface.

These are ideal for polishing and cleaning up soft materials like brass, copper and aluminum. I machined an arbor for these pads so I can run them at slower speeds on my buffing equipment.

Works as they should held up great an got the job done!
