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

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.

Well so far all I can say is very good I cleaned the plate really really good I read guys saying they fell off I am not having that problem 5 thumbs up for the price cant go wrong

Not exactly 12

I rated the adhesion 5 not because it sticks super type but because it comes off easily. It will peel at the edge a bit over time but as soon as you use it it is fine. I have had some that required scraping and acetone to remove them. I much prefer these. from some of the previous comments I was not expecting as good of performance as they provide. I use it on mostly pine some oak and some aluminum. Works on all.

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

I love that it stuck so well! When I needed to change grit, I could go back and forth between sheets and it would re-stick over and over!

These work as expected

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.

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

Works great smoothing aluminum.
