Sackorange 18 PCS 12 PSA Sanding Discs - 3 Each of 80, 100, 120, 180, 240, 400 Grit - 12 Inch Sandpaper Discs with PSA Self Adhesive for Drywall, Floor, Woodworking, Auto for Power Sander

Could not use as the glue does not adhere to sanding disc. No response from company and amazon customer care is not available, makes you question the value of a Prime account.

Great price and the sanding disks are a good quality. These fit me shop smith disc just right. I liked the bundle,with different grits. Suited my needs just right

Like the title says, complete garbage. First disc didnt stick at all. Thought it was my fault. Completely cleaned wheel, again. Second disc would stick for a few hours, but then peeled off. Third time, cleaned wheel with naphtha, again, them with denatured alcohol. Same result. Dont waste your money.

Just what I was looking for.

nice assortment

As a bladesmith, I use a 12 disc sander for a lot of my processes. I have a big Grizzly grinder, and it has TORQUE! I ordered these because Id used PSA discs from Harbor Freight and had reasonable luck with them. These were less expensive, so I tried them. I clean the grinding disc thorough between discs to get all of the adhesive off, so I was suprised when the disc just totally let go while grinding. To my surprise, I found that the sanding disc had basically given up on the adhesive, which was all still stuck to my grinder. So, I had to clean all of THAT off, and try again. Disc after disc, the result was the same. Under the pressure of use, the adhesive just gives up off of the paper backing, leaving a goopy mess to scrape and clean up. I wouldnt use these again if they were a gift. To be fair, though, the abrasive grit seemed to work well, although I wonder if it wouldnt suffer the same type of adhesive failure and just wear off immediately. I never used one long enough to see, unfortunately.

Great adhesion

Works great. Cleaned my sanding disc with acetone and installed perfectly!!

Great product. Couldn’t be happier.

Excellent sanding disks!
