Review on Sackorange 12 Inch NO Hole Aluminum Sanding by Kevin Griffin

As a blacksmith, I use a 12" disc grinder for many of my processes. I have a big grizzly grinder and it has TORQUE! I used Harbor Freight PSA washers and luckily they were cheaper so I gave them a try. when grinding. To my surprise, I found that the grinding wheel had basically given up the glue that was still stuck to my grinder. So I had to clean everything up and try again. Disc after disc, the result was the same. Under the pressure of use, the adhesive simply peels away from the paper backing, leaving a sticky mass that must be scraped off and removed. I wouldn't use them again if they were a gift. To be fair, grit seemed to work well, although I wonder if it would suffer as much. Type of glue error and will be deleted immediately. I've unfortunately never used one long enough to see it.
