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

Great addition to the welding cart, works as described.

Its made by Dewalt, need I say more.

I use these for sharpening my lawn mower blades. They dont take steel of they make them really sharp. Like always name brand last ten times longer than harbor freight

These work great for my boat building project.

Great price for this wheel.

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

Excellent on fiberglass. Really cuts through so be careful. I found controlling it was easy after a little practice. Lasts long time.

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

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

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.
