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

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 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.

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!

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

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.

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.

These discs remove paint and rust very well, but they tend to wear out sooner than I would like. Overall I would recomend them to family and friends.

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.
