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

Used to get clean finish on an edge. Works good.

Great grinding/sanding flap disk. Long wear.

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.

As described

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.

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

Welder must have. These are great,and work great for sharpies lawn mower blades as well.

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.

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.
