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)

Super effective at removing paint! Went through a couple already and lasted a few days of constant use. No large chunks being flung off or anything either. Worth the price.

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

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.

I powdercoat a lot of hitches and need various types of medium to get into all the crack and crevasses before the final sandblast to prepare for shooting the powder. My grinders are Dewalts and they are a perfect size with one exception. The thickness of the pad makes it very difficult to tighten the nut. I have a replacement nut set that works really well for this. I got it here on Amazon (https://www.amazon.com/gp/product/B07QN53R1Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). Its very reasonably priced and may save you some issues. As for how long they last?? Well I have to look at them as a needed consumable. I go through about 50 to 100 a year but these save so much time it is worth it. I took a picture of the before and after of one of the hitch bars. This literally took 5 minutes for all sides. Time is money and these are my favorite tools for removing the slag, coatings or rust from flat surfaces. I hope you find this review helpful. When I saw these with added savings for a ten pack I jumped on it.

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.

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.

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!

Hubby tried this when it arrived and was like wow this grinds fast and no pressure needed. These are amazingly tough. You can go over slightly protruding nail heads and the pad is not harmed. With these, it feels like deep rust and thick old paint melts away. They do wear quickly but thats to be expected.

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

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.
