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

I use these on fiberglass etc, they are great at removing material with great control. They last a long time.

Great grinding/sanding flap disk. Long wear.

I saved a lot of money on all flap disk from this seller but most anywhere else Dewalt 120 flap disk is overpriced

Works well got the job done .

Highly recommend over lower priced disks, this will outlast all the cheaper disks by a long shot. Works great have used quite a bit and still looks new

I use this item for wood shaping and find its is not any better than the Ace Hardware version which is $1.50 less. So if you are trying to save a buck then reconsider your options. They both wear out within a half an hour of steady use. I would think it would be the same on metal for rust and paint removal.

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

Im using it to grind down excess glue off of aluminum tubing, works great for that purpose. Only bit of warning is that if youre grinding dried glue wear a respirator and eye protection. Puts that stuff into a fine mist from the sanding and will get in your eyes. Not pleasant. Otherwise the sanding disc works awesome.

Love these wheels that just screw on. You dont have to mess with taking the locking nut on and off of grinder. Used these pads for years and always loved em. They last surprisingly long. Wont ever get another brand of flap discs. DeWalt cutoff wheels on the other hand, leave a lot to be desired.
