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

Great flap disc. I was able to smooth out the surfaces. Just have to make sure you constantly move or else you will feel the surface uneven. Does the job perfectly.

For my money I always go with DeWalt. These remove material fast and last a long tim compared to other brands. Ive tried a lot of different makes and DeWalt seems to work the best so far. Their cutting/grinding stones are also great.

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 price for this wheel.

I like these but the life span of good grinding seems to be short for the price paid. The benefit though is the ability to grind without grinding hard flat points into the material. With practice you can follow the natural contour of the metal you are grinding. Use these when you want to shape or clean off the surface; used the solid grinding wheels when you need to grind down to get the final shape before using these disks.

Perfect

This cutting wheel may look thin but it cuts through soft to moderately hard metals better than expected. There didnt appear to be any noticeable wear or shedding after initial use. It appears the extra money was worth it.

For the price Dewalt wheels are great. Some places have cheaper wheels, but Dewalts are much sturdier, ie safer.

Makes short work of fiberglass for epoxy repair. I bought 2 of these but the first disc has little wear and should last a very long time when grinding fiberglass.

As expected. does a good job, holds up well and lasts long. Highly recommended.
