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

These things are great! They saved me so much work just on my first project that theyve already paid for themselves. You just need to remember to keep moving at all times or these will make a hole in a hurry.

These work great for my boat building project.

Thank you.

it wears out fast but while it has the abrasive it takes out metal material fast

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

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

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!

Works well got the job done .

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.

Gets the job done
