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

Amazing they all arrived the next day after ordering....to say the least I was impressed with amazon prime!!!

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.

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.

These disks work well. Dewalt made a good, solid product

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.

Works

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

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.

It does what I want

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
