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

These things are great! They saved me so much work just on my first project that theyve already paid for themselves. You just need to remember to keep moving at all times or these will make a hole in a hurry.

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.

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

I guess I was looking more for a solid disc not one that looks like a disc with pieces of sand paper attached to it. For a grinder it may be alright but I was a little disappointed with my purchase.

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.

Industrial quality. Be careful, it may be more aggressive than you imagine. It does the job. You get this guy going at 11,000 rpm and youre removing some stuff.

Bought this to sharpen my mower blades, based on a YouTube video I saw. These work so much better than a grinding wheel. Fast and easy sharpening, wish I had bought these years ago.

Hard to beat dewalt products, I’m hard on grinding wheels and these are long lasting
