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.

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.

Have gone through a few projects using this flap discs. These discs cut through rust with no pressure and will cut through mill scale with a few passes.

The best polishing disc I ever used

The flap disks wear out fast, and I mean FAST.

Great price for this wheel.

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

Great grinding/sanding flap disk. Long wear.

Great addition to the welding cart, works as described.

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.
