Review on 🪚 Woodstock D1309 Sanding Discs - 6-Inch Diameter PSA 100 Grit Aluminum Oxide - 3-Pack: Durable and Efficient Sanding Solution by Brandon Thompson

These appear to be good discs. I bought 12" 120 grit discs for my 12" disc sander that came with 60 grit discs. The 60 grit was too hard for what I needed. These discs are sticking well (it took me forever, but I cleaned the roller very, VERY thoroughly before installing a new disc) and seem to be working great. It's very important to me that the discs were shipped in a flat box, unlike others I've seen that were rolled or twisted to the point where the backing came off. These discs did not have this problem. I haven't had them long enough to know how long they will last, but my first impression is that they will have a typical lifespan. Those were solid disks. The backing is thick enough that I don't expect them to tear.
