5Pack- 4-1/2" x 7/8" Strip&Clean Discs For Angle Grinders-Removes Rust，Strips Paint，Cleans Welds

I'm taking a welding class. I'm also stripping old paint from my home's wood trim. Stuff I've tried for one or both of these two jobs:Prepping metal for welding- wire brush disk (takes too long)- grinding disk (takes off too much metal)- cutting disk (takes off too much metal)- flap disk (doesn't last long)Stripping paint from wood- heat gun (takes too long, risky)- scraper (too hard)- sandpaper (too hard)- foul language (somewhat satisfying, but ultimately ineffective)I figured I'd add these stripping disks to my list of failures, too...Instead, I found they were fast, effective, easy to use, didn't gum up, and took off almost no metal (for wood they're similar to course sandpaper). They also have a fairly decent life - much better than a cutting disk or flap disk.

I have a project truck that's covered in body filler thanks to a previous owner and I needed to strip it all off to remove the dents and damage. I started with a half used 3M stripper wheel, but it only did half the bed side before wearing out completely.I bought these in the hope they would work at least as well as the 3M wheels at a fraction of the price. Turns out they cut through the body filler even faster than the 3M wheels. I stripped the rest of the same side and even went back to clean up what the 3M wheel left. The Duropeak wheel has enough left to easily strip the other side if not more.

I've seen these around for many years but never gave them much thought until recently when I had some painted (thin) sheet metal that needed to be stripped. After watching a couple YouTube videos that raved about them I decided to give them a try.WOW!!! They are amazing! Dang, I wish I would have had these a couple years ago when I was breaking my back cleaning tons of rust off a huge steel structure, using wire wheels, sanding discs, and grinding wheels.I can't make any claims about how long they last, especially comparing them to any other brand, but so far they seem to be pretty durable. I can, however, say that I've never seen ANYTHING strip paint and rust off steel parts like these things!Just make sure your grinder is up for the heavy DRAG they create. I quickly burned up (flames coming out the cooling vents over the brushes) a cheap old Harbor Freight grinder after about 10 minutes of continuous usage. I subsequently found a great sale on a couple DeWalt grinders and they are totally unfazed by the load over extended periods of time.These don't by any means make grinding wheels or sanding discs obsolete but for specific purposes there's absolutely nothing better!!! Once you've used discs like these for stripping/cleaning/de-rusting surfaces you'll never use anything else!

Husband uses for grinding off old damaged paint/stain from our driveway, before re-coating, these work much better then sandpaper and last longer.

These discs work great for stripping automotive paint, surface rust, and older undercoating. Very pleased with the durability and how long they last as far as surfaces stripped before replacement needed. On a VW bug, I did two doors inside and out, two rear quarter panels, and the front and rear aprons on one disc.

I hate writing reviews but these things work great! They take all the paint and body filler off and leave the metal. super fast, don't clog, great price

They definitely did the job of removing paint from metal balcony rails; however, 3 out of 5 disks were larger than others and touched the guard of my angle grinder which lead to pretty bad vibrations. Vibration decreased as the disks were grinding down which is good but unfortunately they were doing it way too fast and I ran out of them before I finished removing all the paint so I had to order another round. Different ones this time, hopefully they will perform better.

Works well to remove Mill scale and paint without grinding the metal. Definitely worth every nickel, was impressed with the performance in the durability of the pad.
