10Pcs 180 & 320 Grit Scour Flap Disc 4 1/2 Inch Angle Grinder Attachment for Metal Wood Scuff Grinding Sanding Discs Scouring Pad Polishing Wheel Paint Rust Remover

I bought these to refurbish a couple of cast iron table saws that I bought and they turned out to be perfect for the job, not too aggressive, and left the tables with a perfect satin finish. I only used one of them and it still looks almost new so I’d say they hold up quite well.

This material often referred to as Scotch-Brite. I first saw this used for aircraft corrosion work in the Navy way back in 1975. Back then it was “state of the art” and expensive. I use this on Aluminum Boats to remove a layer of corrosion measured in microns. With a common grinder, this is pretty quick work. With a wire brush type wheel you are likely to take too much material off and leave scratches. I use the burgundy colored, since it’s not as aggressive as the green. These hold up very well and the price is reasonable. As always, wear safety glasses and a dust mask.

Good packaging, fits most grinders, works really well for surface preparation

Great value.

Did the job...but, it took all of them. thankful it was only a couple of bicycle parts...

used these to remove paint on my tractor worked very well but throw a lot of dust so put a mask on so you do not breath dust

Work great

Attempted to remove a coating from a circular piece of steel. This 180 grit disk was pretty much destroyed in less than 4 minutes of use. I was using a Bosh variable speed angle grinder on a moderately low speed #2 on the grinder speed wheel. I have used far better abrasive pads that lasted much longer for not all that much more money. I think the better password be a better deal. I can’t recommend these pads for metal work.
