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

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.

These are excellent.

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.

works ok

Ive been using the disc to sharpen mower blades. Works great. Sharpened four 21 blades and still looks new. I suspect it will last me a long time with my limited use.

Sands well

Second time buying these and would buy again. A great option. Lasts way longer than regular sanding pads so worth the extra money.

Perfect

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.

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