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

Great for polishing mosaics,seem to hold up well

Durable! And got the job done!

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

For the price, it's hard to justify spending more money. Do these last as long as well made American or German brands? No, however, these are 25% of the cost of name brand discs. Just remember to wear a respirator or a well fitting mask as these throw a lot of material and dust.

Definitely saves on time

These were not particularly useful or durable in my application. Even at the proper RPM, I found these pads tended to kick, bind and burn the surface when used to remove finishes on wood. Check the specifications on your angle grinder prior to purchase, and check the composition of the material you intend to use these pads to remove. I used a motor speed control on my angle grinder, which natively operates at 6700 RPM if uncontrolled. Many angle grinders operate beyond the manufacturer's recommended 5000 RPM speed, which could result in a hazard to the user. As always, use of eye protection and a mask is a must, especially in a confined area.

Great item

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.

They clean up steel nicely, but they don't last very well. Good product for the price.

Well made and easily removed paint and rust without cutting into the metal and great value

Works well on clean up of engine block, paint removal

work well and hold together

bought these to clean up some stainless steel exhaust and alloy parts, these fit standard grinder work a treat and last ok,so mush easier than polishing by hand, recommend
