POLIWELL 150 PCS 3 Inch Sanding Discs Silicon Carbide 400-10000 Grits Wet/Dry Hook and Loop Sandpaper for Drill Grinder Rotary Tools with 1/4 in Backing Pad, Wool Pad and 3pcs Soft Foam Pads

These are good quality sanding discs for sanding wood turned bowls and other turned items. Tried some that were less expensive and the sand paper left too many marks in the wood. These sanding discs dont leave any marks and allows me to sand through the grits and get a great smooth surface before applying the finish. Sanding is an important step for woodturners and these quality sanding discs allow me to turn out a better product.

Used them on motorbike headlight, worked good after i learned to use the foam pads you put under the sand paper.

review

Got this to restore headlights and they work very well at least of the grits that I have used. I’ve only used 5 different grits so far but these did the trick and the lights that I cleaned up went from hardly shining light 20 feet to like new and crystal clear.

Im getting my 1976 Alfa Romeo Spider ready for a re-paint. These small disks are just the thing for the small-area curves and spots on the car. Im always cautious about new sand papers - because a bad grit can make nasty marks!!! These disks have a nice felt backing that latches nicely onto the hooks of the sander face - and stays on at high RPMs. Price seems OK for these, IMO.

Great discs. Dont last to long though.

Good deal for a near lifetime supply of pads.

Worked just like the expensive 3M discs that Ive used in the past. Great value!

I was excited to find something inexpensive to place on my drill to avoid having to pay 500 to 3000 dollars for a cabbing machine for my rockhounding hobby. Silicon Carbide is supposed to have a MOHS hardness of 9. I was standing sunstone 400 grit. I tried wet and i tried dry. In both cases the sand paper lost its ability after 30 seconds. So to me this product is either poorly made, or not really Silicon Carbide. I ended up having to use my sand paper meant for my orbital sander. But I need to buy a finer grit. I think that my orbital sandpaper is made of Aluminum Oxide. Just to note my sunstone was already smooth. I have a lack of confidence that the other grits are what they claim to be on the back. Chalcedony MOHS 7 (Jasper, Agate), Quartz MOHS 7, Topaz MOHS 8, Labradorite MOHS up to 7.2 (moonstone, sunstone), Peridot MOHS 7, Garnet MOHS 7.5 to 8.5, Opal at best is 6.5 MOHS. Maybe others have had better experiences, mine was a disappointment. I left 3 stars, 1 for price, 2 for adapter for drill, and the 3rd star because the sandpaper can still be used for wood and other soft material(plastic). I didnt leave 5 stars because of possible false advertising, and the 4th star is gone because of poor quality in my opinion.

Hook and loop made for quick disc changes. I use these with a flexible backing plate for headlight restoration.
