DEWALT DW8311 4-1/2-Inch by 5/8-Inch-11 36 Grit Zirconia Angle Grinder Flap Disc

Thank you.

Beats the price at the big box stores- hands down. I got my purchase fast and was able to use this to cut the top off of one of my kegs to make a keggle. I highly recommend this item.

Good quality

Bought them for that purpose and they work like a champ. I like that they dont take off a lot of metal like a grinding disk does. Im sure Ill find other uses for them. Sharpened two blades and see a bit of wear, but i guess that is to be expected.

Expecting a great flap disc because its Zirc diamonds and its expensive. But it seems just the opposite. The cheap discs cut much faster, leave the same finish, last longer. The cheap discs cut faster. Whether removing paint, mill scale etc or more heavy use removing metal, grinding welds, the cheap discs do it notably faster. With the cheap disc you can run the grinder down the work and make a wide stripe of sanded area. With the DeWalt, you try and run a stripe and you get a really thin sanded spot flanked by a scuff mark. The cheap disc sands a stripe about 4-5 times wider than the DeWalt. The cheap discs last longer. On the DeWalt disc, the area near the edge of the disc becomes worn down and very shallow VERY quickly. The Other discs wear much more evenly. Once the DeWalt is worn, its like grinding with the EDGE of a regular grinding wheel. You no longer get that brushed metal look to the work that you expect with a flap disc. The DeWalts and the cheapies are both China made. Im going back to the cheapies.

Great price for this wheel.

I bought these to prep metal straps for a welding bend test, and they do what they are supposed to do and they seem like they last a little longer then the previous brands that i have purchased. The price on amazon seems to be a little lower than what they are at the stores in my area.

Bought this flap disc sanding wheel to specifically work with the Makita dust shield that I am using on a cheap Kawasaki 4 1/2 variable speed grinder that I got on Amazon. The dust shield attaches to my vacuum and really helps keep the dust down when Im grinding on fiberglass.

The flap disks wear out fast, and I mean FAST.

I was suggested this product for sharpening lawn mower blades, it fell apart before I even got done sharpening one blade. Might work alright for a more gentle application that doesn’t include shaving metal. Back to the trusty grinding wheel.
