Mornajina 10 Packs 4-1/2" x 7/8" Strip Discs Paint Stripping Disc for Angle Grinders, Paint Remover for Metal Wood, Paint Stripper, Remove Scaling and Oxidation(Assorted Color)

What's not to love? These work, cheap throw aways and so a good job with angle grinder.

They do work well, but not as durable as I hoped. I imagine on the metal I’m using them on is the hardest. I do like themMy makita has a small wrench, and these are thick, so it won’t work well, not this products fault, so i us a nail with my wrench to get around the thickness of these.

I use these to prep for welding. They clean up the metal nicely.

This multi-pack of stripping disks is a bargain and they work just as well as the ones I picked up locally. They seem to hold together really well and they are nice and aggressive on paint and rust, but don't eat away at the base metal hardly at all.

I think I use these more on my angle grinder than I do flap discs. They strip paint and scale so easily. If you're not careful, you'll start taking away metal. I keep these all stocked all the time.

I ordered the “Mornajina 10 Packs 4-1/2" x 7/8" Strip Discs Paint Stripping Disc for Angle Grinders, Paint Remover for Metal Wood, Paint Stripper, Remove Scaling and Oxidation (Assorted Color)” to review and to use to remove all of the rust on my fabricated fire pit. These are better than grinding wheels or flap discs because they do not produce any sparks. However, they do wear out a bit quicker and they are more expensive than the same sized lower end flap discs. I like that they also seem to remove the rust without removing the steel and leave a nicer surface to refinish. NOTE: I do not believe there is any grit difference between the colors.Explaining my rating system:5 – Exceeded Expectations – Highly recommend product.4 – Average to Above Average – At least what you would expect based on the Product Page.

Low quality or questionable safety issues. Not recommended.1 – Junk – A complete misrepresentation of the product advertised, severe quality or safety issues. Avoid at all costs.

I have used these discs for so many projects in the past. To me, they replace a sandblaster for the majority of projects. I do not own a sandblaster so any time i want to do a metal restoring project, this is the way to go for me. It is not hard to get down to bare metal using these and an angle grinder. One place they do fall short in is you are not going to be able to get into detailed areas. Most of the time though, those areas still have solid paint in tact.

What did I buy? What does the color represent?I think that purple is less aggressive than blue. Maybe?The description fails to explain what I bought and no documentation or sticker explains that in the packaging either. No labels on product.
