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

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 used several of these (60 grit and others) for grinding welds, deburring, chamfering and similar tasks. These are pretty good - they cut quickly, leave a decent finish, and last a while. That being said, I prefer the Walter 15W456 - they cut a bit more quickly and you can trim them when theyre used up to get a bit more life out of them.

Buen producto

Bought this to sharpen my mower blades, based on a YouTube video I saw. These work so much better than a grinding wheel. Fast and easy sharpening, wish I had bought these years ago.

Ive tried to sace money using less expensive brands but I end up have to change out the disc more often which at the end I spend more money. This dewalt disc is definitely worth the money

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.

I was suggested this product for sharpening lawn mower blades, it fell apart before I even got done sharpening one blade. Might work alright for a more gentle application that doesn’t include shaving metal. Back to the trusty grinding wheel.

Works well got the job done .

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

The best ive found. used mostly on carbon steel tube and hot roll steel sheet. They last a long time. even at the end of life and hard as a rock, they are still perfect for deburring or chamfering.
