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

This grinding wheel did an excellent job at grinding the welding areas 3 time faster and also smother then a standard grinding wheel.

Amazing they all arrived the next day after ordering....to say the least I was impressed with amazon prime!!!

Used this to clean up some thick metal brackets and it did great! Very smooth and easy to control. Used it on 4 brackets total and looks like it still has quite a bit of life left so will definitely buy more in the future if need be.

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.

Is not the same threads as one bought previously- so if you dont use it immediately are your just out of luck? please take a look at my previous Dewalt (and other) 5/8-11 thread purchases- there is something wrong with this disc

Works

The best ive found. used mostly on carbon steel tube and hot roll steel sheet. They last a long time. even at the end of life and hard as a rock, they are still perfect for deburring or chamfering.

This disc powers through lawn mower blade sharpening. Makes quick work with quality results.

I used this with a 4.5 Inch DeWalt Grinder. It installed easily and I didnt find that it slipped at all. I like the flaps because it allowed me to have a more smooth finish on the aluminum I was working with compared to a traditional grinding wheel. It doesnt bounce when you press it against the surface.

Works well got the job done .
