Flap Disc 4 1/2 inch 20 Pack for Angle Grinder Sanding Disc Assorted Grit 40 60 80 120 Aluminum Oxide Sanding Grinding Wheels 4.5 x 7/8 Inch Flat Type #27

Have had no issues with the cutoff disc. They work well for me.

Cuts great.

multiple grits. works great on multiple materials.

Sure is nice to see how much they really care! The wear pattern/marks don't seem normal, I'm guessing sure to the low quality! On the other hand 20 for less than $20 is a good deal of anything!

Good value for the buck. This was my first use of a grinder so not sure about comparing to other brands but it ground off 1/8th inch of aluminum at the top of my sticking door. I used just one and now the rest are a storage problem.

After reading some of the reviews, I thought that I would be going through at least two wheels of the 40 grit as I completely resurfaced a corroded cast iron pan, but I got it done with plenty of abrasiveness left on the first one. I probably didn't need to get this big multipack... but now I have tons of flap wheels for other projects!One note: they do send 5 of each grit, even though the description says: "our 20 pack contains 10 pcs of 40 grit, 5 pcs of 60 grit, 3 pcs of 80 grit and 2 pcs of 120 grit" alternative facts?

My husband has bought these before. There is one size he uses the most but this is a good value regardless.

I do a decent amount of welding, so I end up having to use these on metal frequently. These hold up surprisingly well, and are far better than other bargain brands. I fully plan to make these my go-to brand for cutting, grinding and sanding disks from here on out.
