Mornajina 10 Packs 4-1/2 x 7/8 Strip Discs Stripping Wheel for Angle Grinders, Paint Removal Disc, Rust Stripping Wheel, Remove Scaling and Oxidation(Purple)

These are Chinese made, and last 3 mins on concrete. I’d need 100 to finish my small porch. I’d save my money if I had another chance.

They came packaged in 2 sets of 5 pads. They look like a hard sponge like material. I attached it to my angle grinder and tried it on some wood that had paint on it. The pad took the paint off with ease. It will leave little swirl marks in the wood, so Sanding after is a must. It did a great job and I see 1 pad lasting for a while. I think it will also take stain off wood, but may take a little bit longer due to stain penetrating the wood and the pad may have to work a little harder. The picture I attached did that little section in about 20 seconds.

Great product for stripping many layers of old paint!

The abrasive pads are not concentric with the backing disk. When used, the grinding assembly is out of balance and vibrates. Sloppy assembly.

If youre looking to clean a surface of old paint and rust before you weld or paint it, these are fantastic. Theyll make short work of it and fit my little off brand grinder with no problem. These are a good value- but use as light a touch as you can in order to get the most out of them. 5 stars, will buy again.

Ive used these so far for general paint removal from metal and they work very well. It pulls it down to white metal in no time and doesnt get too hot if you keep the pressure right. They easily spit the removed debits out so be mindful of where thats going,a bit messy, but the stream of dirt is what keeps these free from clogging and lasting a long time!

These grinder discs are a must have to remove paint before welding. They remove rust and paint with ease. They work on any standard grinder.

I am Stripping the paint off my house and we have been going through paint discs like water. This brand is well-made and lasts a lot longer than the other. Highly recommend.

I bought these discs to remove rust from some metal plates. They work okay but wear very fast,therefore the 3 star review. I will try another brand on my next order.

I work on old air-cooled VWs (hobby not professionally), so Im pretty familiar with stripping down paint and rust. Ive used these kind of stripping wheels before. These are a fairly aggressive grit so they wipe away even the old hard original paint fast and handle surface rust quickly. These can take off some metal too if you go heavy with them so like most tools like this you have to use light pressure and let the tool do the work. They seem to have a pretty good life before theyre too worn out to keep using and the price point for 10 is very good. Im fairly cautious with 5 star reviews. I only give 5 stars to a product that has exceptional quality features, exceptional value for the retail price, or both. These have good service life and last pretty well, they do the job, and the price is good. Thats a 5 star product in my book!
