Great value. Held up well during use to remove epoxy grout haze from ceramic tile.

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.

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

Recomiendo no usar otras lijas que no sean las del kit

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