One one of the disc for every grit is labeled. With no way to tell the others of which grit they actually are. Because the rest have no labels.

I use flapdisk for cleaning up welds. For the price, these do an extremely good job. They last a decent amount of time and do not melt with too much heat.

They work great, last a decent amount of time/work, and remove material superfast. The amount of work I can do for this price is surprising to me

They are definitely made cheap but for a dollar each they will do just fine. You might be able to get away with using one disk per project, I would be surprised if you could get anymore use out of them beyond that. They will be nice to have around the shop as extras.

These are thinner than the images make them out to be but still a good wheel. Packaging could be a bit better but Amazon also sent them in a bag instead of a box. The first 2 had damage from shipping to the backing plate that made me nervous about them coming apart during use so I skipped them and went deeper into the pack to test. Otherwise these are great for around the home garage projects. They removed dross from plasma cut parts with ease and didn’t burn out overly quick to comparable wheels I’ve used in the past.

These Flap discs work as good as any I have used. They are a perfect fit for all of my grinders and have a decent life when grinding metal. They are gritty enough to remove material quickly.

I've been removing the finish and rust from a utility trailer. Trying to get it stripped down to paint and install a new deck. It was in really bad condition. The difficult thing is that the trailer was powder coated at the factory. The finish had failed so there was rust spots everywhere. It needed to come off. When I tried using a regular grinder disc or sandpaper, it would heat up the powder coating and get instantly clogged. Paint removed didn't work all that well either...I've been using these discs to do the job with great success. They are course enough to chisel off the coating but not so much that I'm aggressively grinding into the steel framing too much. It's making a frustrating job go relatively quickly now. The nice thing is that these last a very long time. I've gotten most of the finish off and cleaned up some welds, and I've only just worn through my 3rd disc. Very happy with these.I wholeheartedly recommend these grinding discs. I really can't find anything negative to say about them. Great seller, outstanding product, and fast shipping from Amazon. Order with confidence!

These flap discs work very well for removing surface rust and cleaning. They come in four grits suitable for most sanding and grinding applications. The discs grind smoothly and do not generate a lot of heat.
