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

I purchased this to sharpen my mower blade. It worked exactly as intended. Only took a few passes to produce a clean / sharp blade. Cant ask for anything better. Seems to be well made and the price was reasonable. Highly recommend for sharpening mower blades. Use PPE and safety guidelines for angle grinders!

Really smooth, nice grinder disc. Much better than those supplied for free with my grinder - which I used first then finished up with this one. I could have done the whole job with just this disk. It has a bit of flex to it which is nice to get into tough areas with high curvature. Definately recommend this disc to anyone.

It does what I want

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.

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

This disc powers through lawn mower blade sharpening. Makes quick work with quality results.

Grinding flap disk of a quality you can count on. Once you learn how to use these disks they will become a favorite abrasive tool.

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.

For my money I always go with DeWalt. These remove material fast and last a long tim compared to other brands. Ive tried a lot of different makes and DeWalt seems to work the best so far. Their cutting/grinding stones are also great.

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.
