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

Perfect

I saved a lot of money on all flap disk from this seller but most anywhere else Dewalt 120 flap disk is overpriced

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.

Very high quality. I save this for the finishing touches

it wears out fast but while it has the abrasive it takes out metal material fast

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.

works fine exactly what i need.

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

I havent used other flap discs so I cant compare but I was pretty happy using it. It didnt last as long as I wanted which is why I gave it 4 stars instead of 5. I did order another one I liked it so much. I plan on trying other ones and comparing- after I do I might change this review. I used it to smooth out my terrible welding skills and it did great. I tried it on truck bedliner though and it heated it up too much. It turned it into wet tar and made it harder to take off. But I didnt get it for that anyways. Works great on metal.

Great product. Just used once, but attached to my Dewalt grinder and sharpened a lawnmower blade in about two minutes razor sharp. Sure beats grinding away with my old dull file for 30 minutes. Will be ordering more of these for other uses. Seems like it will last along time too.
