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

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

Beats the price at the big box stores- hands down. I got my purchase fast and was able to use this to cut the top off of one of my kegs to make a keggle. I highly recommend this item.

Im serious about blade care and these discs are the best way to hone a blade without taking off too much material. They last a long time and are easy to work with.

I have always used these types of grinding discs for cleaning up metal surfaces. They dont chatter and when light pressure is applied the surface is polished. They work better and last longer is pressure is kept to a minimum so the work piece doesnt heat up, even just the pressure of the grinder is enough as these discs remove material quite fast.

I bought these to prep metal straps for a welding bend test, and they do what they are supposed to do and they seem like they last a little longer then the previous brands that i have purchased. The price on amazon seems to be a little lower than what they are at the stores in my area.

If you have used these before, you already know how effective flap disc sanding is. It cuts through metal, or wood, or anything else in a surprisingly quick, yet controllable manner. If you need to remove a lot of material from a flat surface this is a good way to do it, of course you should also have other sanders to prep a finished edge. This is more to burn through a lot of wood or metal and it is very coarse, so you need to be cognizant of the amount of pressure you are using. Always taper the pressure off for awhile before you move to the next grit/sander otherwise you will have some deep gouges. If you havent used one, and you have an angle grinder, this is a good way to expand your tool-kit cost effectively. You can do alot with an angle grinder and even more if you have the right discs.

It works, nothing too special. I find the cheaper Home Depot discs just as effective. I am using it to take off old paint on a steel toolbox.

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.

Great deal and great product!!

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.
