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)

Great product for stripping many layers of old paint!

These work really well. The problem is they wear out rather quickly. I used a wire brush on an angle grinder first and then finished with these. That worked. I do recommend them with the limitations I listed. The price is good compared to what they cost in big box stores.

Like this product removes a lot of rust, and wears slowly would recommend to anyone

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.

Works great be carefull will take all paint fast

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.

This is a pack of 10 generic purple stripping discs packaged as 2 boxes of 5 discs. Theyre mainly used for stripping paint and rust without damaging the underlying surface too much. Neither the discs nor the packaging have any markings whatsoever. I measured the discs at 4-1/2 diameter, 7/8 arbor, 1/2 abrasive thickness and 3/4 overall thickness. The product listing has different specs in different parts of the listing which is confusing to say the least. Most concerning is the max RPM which is listed as 12500 in one part of the listing but only 11500 lower down. My angle grinder only does 11000 RPM so these will work fine. When fitted to my grinder the discs almost touch the inside edge of the guard. They also are thicker than the guard and extend out past it about 1/8. That allows them to be used across their entire surface but makes me worry what might happen if one comes apart in use. I tried them out on some painted scrap wood panels and old rusty metal frames. They made short work of the painted wood exposing smooth bare wood in literally seconds. The rusted metal cleaned up just as quickly, and unlike sanding discs didnt leave flat spots. These are now my go-to discs for cleanup work. The price on Amazon is currently $40 for 10 which is about the average cost per disc for this type of product. Assuming they all perform similarly to the one I tested this will be a good value overall.

Purchased to do some paint stripping on the inner fenders of my VW project. They easily attach to my 4 angle grinder, and make quick work of stripping down the old finish. The price is good, and you get 10 of the disks. Overall their life span seems pretty good. I used 2-3 of them for my project, and have the rest on the shelf for the next project that comes along. Would buy again.

Easy paint removal on steel and wood, takes off power coating on metal quickly and easily. Perfect for cleaning oxidation from metal prior to welding and can be used to remove splatter after welding. Non-clogging so work stoppages are minimal. Grit is not marked but purple is typically used for paint, rust, and corrosion removal.

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!
