30 Pack 8 PSA Sanding Discs Set - 5 Each of 80, 100, 120, 180,240, 400 Grit - 8 Inch Self Adhesive Stickyback Sandpaper Discs for Drywall, Floor, Woodworking, Metal

With the first one I tried, the adhesive was all lumpy after peeling back the paper so it would not have been flat on the disc - threw it away. With the second one (same grit), I got it on but it would not stay on, kept peeling off - threw it away. Third one (different grit), it went on, stayed on, and works fine. So maybe some grits are okay, some are not, dont know, but Im expecting to get 50% yield at best. At the price, maybe thats okay if you dont mind wasting the time messing with the bad ones.

price and availability

Look just like the original disc that came on my 8 inch porter-cable sander, very nice! I got the assortment and a smaller pack of the most used grit.

These sanding discs have terrible adhesion. I got one to stick to my alcohol-cleaned 8 aluminum power sanding plate by heating it up a little with a light touch with a torch but a week later its lifting off and is causing unsquare sanding.

Just what I ordered

I have not had the time to get the feel of the wheel on the side . The 42 inch long sanding dish I handle very well. The wheel will help me with sanding.

Good

Convenient self sticking. I would like to buy specific grits separately because I use some more than others

THe problem is not with the sand paper, but with the glue that was selected. Large gobs of glue are left on the 8 sanding disc and its nearly impossible to remove. Im throwing that paper out.

Very satisfied
