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

Worked as expected for sanding very distressed hardwood floors.

My disc sander had a sheet of sandpaper on it that I used relentlessly for over a year. I have already gone through 2 sheets of this stuff and my results are not great. The sandpaper becomes worthless after very little use. Huge bummer

Works great smoothing aluminum.

very tough to get off the metal disk, but I guess that means it sticks well

Great price. They seem to work fine on stuff Ive sanded. I would recommend them

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.

Poor product

Look fine. Not used yet.

Grit appeared reasonably hard wearing easily cleaned with an abrasive cleaner. Good value.

had to make my own backing plate
