Flap Discs 40 PCS 4.5 Inch - 40 60 80 120 Grit Grinding Discs 4 1/2 Assorted Sanding Grinding Wheels,Aluminum Oxide Abrasives,Grinder disc

I have found these disks have staying power, and do a great job at eating through old paint.My only complaint is more about a user error than about the product. In my over zelous utilization I did manage to sand deeper into the wood than I would have liked. In my joy to have found a product that would work on this demon of a garage door, I often pushed too far. The important part of this story is that it was this product which allowed me to finally send the demon spawned paint on my garage door to the pits of hell. This was after innumerable other product failed, to include strippers, sanders, heat guns, razor sharp scraping tools and other implements recommended to remove stubborn paint. I thought I would be defeated and forced to remove the wooden doors and replace them, but alas victory was mine.Superior product for the price point.

Great variety pack! I used the most course disc for a wooden deck restore job. Sanded all surfaces of the deck and barely used a handful! Very durable!

I knew what I was getting when I purchased these for so cheap. They are not a very thick flap and they wear down fast. For the price and for small jobs they are great. If you are looking for a professional tool look elsewhere. Basically they very cheap but work for small jobs that don't require extended usage.

Great set! These discs hold up well to name brand competition

I've always used a wire wheel to clean up my welds. I still use the wire wheel, sometimes, but for the most part one of my grinders is dedicated to flap disc use (another grinder has a thin cutting wheel on it, and the other usually has a thicker grinding disc on it).The flap discs definitely don't last and last, but man do they work nicely. No grabbing the work and making the grinder jump in your hand. They take off metal reasonably quickly but at an easily controllable rate. Perfect for cleanup.In case you're an idiot like me - don't use the flap disc on just-welded metal. It's really hot and will probably wear the disc much more rapidly. Go clean up the previous weld first, then this one.

These are doing the job! I have bought different discs to strip multiple coats of paint from a building with wooden car siding. These have been the best, cost effective, efficient discs I have tried so far. I can strip at least 15 sqft before the disc shows any wear. I need to swap out around 50 sqft of use. I am taking the siding down to bear wood to stop fresh paint from peeling so fast.

Works like a champ on metal, but on soft wood they disintegrate and hit me in the chest. But works as good as a harbor freight flap disks.

Absolutely love these
