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

excellent product

Delivered as promised - the adhesive on the back isnt super stick and comes off easily. Good quality - fit my ShopSmith 12 disc sander just fine. Peels off slightly on its own. Could be me - could be the adhesive. Maybe Ill clean the disc with acetone before I apply the next one.

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

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.

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

These work well on my 1948 Shopsmith 12 sanding wheel.

Great adhesion

It sticks, it sands, and seems to be pretty durable. I even sharpened some chisels with the 110 grit. Good product.

Bought these for use on my DIY Disc Sander I built for my Wood lathe. Excellent adhesion to plywood and after sanding I hit it with the edgewood stick. Have had no issues so far!

Poor product
