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

Just what I needed. Sands out scratches in liquid glass coating and then buffed them to perfection. Cant see where the defects were. All glossy as if perfect from the start.

Alot more pads than I thought.

Love it will shop again

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

Good deal for a near lifetime supply of pads.

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.

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

I ordered this to restore my headlights on my car. They held up great. I wet sanded as well as dry sanded. No problems with pads. I used most of the pack since I wanted perfection on my headlights. Good value here. Much cheaper than new headlights. I highly recommend these.

As good a sanding wet/dry disc as Ive ever used, grest price will buy again. Rod

Theyre actually pretty good quality they work well for me. The price is usually less than the name brands.
