NUODUN 10Pcs 180/320 Grit Nylon Fiber Flap Disc Metal Polishing Wheel, Abrasive Buffing Grinding Discs for 4" Angle Grinder, Deburring and Rust Removal of Welds on Complex Surfaces

I got these for cleaning and semi polishing a stainless steel kitchen flattop. They were perfect for getting the surface very smooth. Which definitely aids in the non stick functionality. Good value and are fairly long lasting.

works great shines polishes, leans up blimashes

I already had some 4.5" versions of these that I was very impressed with, and saw these were MARGINALLY cheaper. I did not realize that they were 4" rather than 4.5". Once they showed up and I opened the package, I was met with an immediate feeling of disappointment. They were quite notably smaller than the others I had bought for VERY LITTLE additional money. I measured them and they were not quite even 4", I think that they were 3 7/8" or something. Anyway - the product is fine for its intended purpose, but when a 4.5" fits in the tool and costs so close to the same, these just are not worth buying.Best used for buffing, polishing and surface preparation jobs. These are NOT grinding disks. If you expect to do heavy material removal, you will be sad to have spent money on this. If you want to clean something up nicely to prepare for paint or polish, these are the type you need.Flexible, not stiff like some. Better for contours, but they do not last as long.

The media could not be loaded. This item is great for cleaning up Metals and aluminum. it’s speed up the process very quickly as I used it on a angle grinder instead of a buffing wheel. Keep in mind that a angle grinder cannot get into all the nooks and cranny. You only need a smaller rotary tip for that. I mainly use this to smooth out the metal and get it ready for buffing.Overall, it’s a great item to have. If you do a lot of polishing work it really does speed up the process very quickly as a angle grinder is very strong and maybe a little too strong. When you are using the angle grinder, you have to be very careful not to shave too much off the metal that you polishing.The wheels lasted pretty long and I only have to use one wheel for my projects. With a 10 pack, it should last a very long time for the average person.The quality seem to be very good, and I wouldn’t hesitate to buy this again.

These work as intended and are ok-ish on quality. I do wish they were labeled for grit, just as a courtesy. My grinder uses a 7/8 arbor so I wasn’t able to center these perfectly, but they still worked by getting them as close to centered as I could. They polished up my axe head well though after working up from 80 to 120 grit on some flap discs. The photos show the head after the 120 flap disc, and then after the 180 and then 320 grits. I’d say they are priced well for the quantity and quality combined.

I tried, sanding, heat gun, chemical, and scraping. I couldn't get that paint off until I got these and put them of my angle grinder.

I bought a pack of these and they are garbage. They disintegrate so quickly. I used it on axe heads and similar tools made of steel. Yes they technically worked, but I’d recommend paying more money for a product with better durability.

Great for surface rust. Wish we would've had these disc years ago sanding rust on cars.
