Works great

Fast shipper, excellent price, couldnt be happier

not enough time to tell yet, have just put it on my disc machine and did a hobby project so dont have enough time with this item to be real truthful on how it cuts or how long it lasts or if it can take the abuse a normal shop puts on it....hoping so

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.

not enough adhesion had to buy 3 m adhesion or return them qne fell off before turning on sander

a clever selection of levels of abrasiveness, fits my machine well

what I expected and on time

As long as you clean the surface well these seem to stick pretty well they do wear out relatively quickly and getting them off is a chore.

worked very well on my shopsmith sanding disc

Like the title says, complete garbage. First disc didnt stick at all. Thought it was my fault. Completely cleaned wheel, again. Second disc would stick for a few hours, but then peeled off. Third time, cleaned wheel with naphtha, again, them with denatured alcohol. Same result. Dont waste your money.
