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

I bought this for my angle grinder to sharpen my lawn mower blades. Works great.

Works great for sharpening lawn mower blades, without being too aggressive…

This was my first flap disc. Im surprised at how much manufacturing and tech has to go into making one of these gizmos. Theyre pretty well connected with high quality tech and materials in order to function properly. Dewalt (Black & Deckers commercial grade products) did OK on this one. FYI: Black & Decker = residential grade Dewalt = commercial grade ... SAME COMPANY!

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.

Bought them for that purpose and they work like a champ. I like that they dont take off a lot of metal like a grinding disk does. Im sure Ill find other uses for them. Sharpened two blades and see a bit of wear, but i guess that is to be expected.

Product works good the only things is I received one that screws on the grinder it self not the one in the picture

Works very well, does not last long though so order plenty. I dont know how I ever did car restoration before without these. Removes paint quickly, removes rust pretty well too. Very fast paint stripping. Also really good for finishing body seam sealer or panel adhesive where you need to level and pretty it up.

Hard to criticize this product. Love not using wrenches to change wheels out and is long lasting

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

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.
