My 12" disc sander launched its pad a couple weeks ago because the adhesive failed. It's okay as it was at least 5 years old. I am now looking for a good replacement. I see Powertec all over the place but it looks like the coarser grits get complaints of weak adhesive. Any suggestions on a good value brand for a casual/hobby metal fab guy like me?
Good value discs for my 12" disc sander?

I have some Klingspor discs that work well. No adhesive failures.
Personally I use THESE
If it tells you anything, I purchased them February 2014 and have not gone through the entire pack yet and have had quite a few metal projects since then. I will admit though that i 100% get every bit of life out of a disc before ripping it off. Probably costs me some time at the grinder, but, Im not working on the clock and its my money, so
These get used on basically every single job to true everything up after cutting, so they most certainly see some use.
For removal, I just grab a torch and a pair of pliers and rip it off. Kind of a pain, but I dont know what else people expect from a piece of sandpaper glued to a backer. I will tell you that these damn things are NOT coming off without you forcing them to come off.

A few years back, I bought a ton of high quality, 80 grit, 16"wide sanding belts, at a liquidation. For my disk sanders, I cut a piece to the proper size, spray the back with 3M #77 spray adhesive, and press the sand paper on the metal disk. I've never had any problems and it's much cheaper than the price of pre-cut, PSA sanding disks.
