Review on 🪚 10-Pack POWERTEC 110580 9-Inch PSA 80 Grit Aluminum Oxide Adhesive Sanding Discs: Efficient Sanding Solution by Eliot Wahl

Don't waste your time or money on this. They're supposed to be 9 inches tall, but they actually measure just 8.75 inches, leaving nearly 8 inches of exposed steel plate spacing on your 9-inch grinder. Worse, the glue didn't even stick. I removed the old sandpaper and cleaned the steel surface very well on the sander leaving no trace of the old glue and the new sanding disc glue failed before I could even use it. Seems to stick well. and when I tried to use the grinder the next day. Most of the disc has already started to delaminate. The object adhesive just didn't hold. I will return them including the drive I wanted to use. A shame. the price is insane, but it's a shame if the size isn't real 9 inches and the glue doesn't work.
