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)

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

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.

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.

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.

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

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.

Pardon my mistake for not getting the before picture (obviously the after is now useless, opps). Ive been driving the same Jeep in the Midwest for almost 21 years, so there is rust, no matter what i do. Before any repairs, i always have taken care of old rust and in the past, have used the strip disks that attach to the drill. Not no more. Wow, between the combination of using the angle grinder and these disks, i was able to get thru what i needed to in a shorter amount of time. Very impressed and they didnt break apart or deform when i used them. I thought the 10-pack was a good value when i saw it, especially considering what i have spent on single drill discs. Granted, its probably gonna take me a long time to use them all.

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 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.

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!
