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

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

Excellent on fiberglass. Really cuts through so be careful. I found controlling it was easy after a little practice. Lasts long time.

Used this to clean up some thick metal brackets and it did great! Very smooth and easy to control. Used it on 4 brackets total and looks like it still has quite a bit of life left so will definitely buy more in the future if need be.

Expecting a great flap disc because its Zirc diamonds and its expensive. But it seems just the opposite. The cheap discs cut much faster, leave the same finish, last longer. The cheap discs cut faster. Whether removing paint, mill scale etc or more heavy use removing metal, grinding welds, the cheap discs do it notably faster. With the cheap disc you can run the grinder down the work and make a wide stripe of sanded area. With the DeWalt, you try and run a stripe and you get a really thin sanded spot flanked by a scuff mark. The cheap disc sands a stripe about 4-5 times wider than the DeWalt. The cheap discs last longer. On the DeWalt disc, the area near the edge of the disc becomes worn down and very shallow VERY quickly. The Other discs wear much more evenly. Once the DeWalt is worn, its like grinding with the EDGE of a regular grinding wheel. You no longer get that brushed metal look to the work that you expect with a flap disc. The DeWalts and the cheapies are both China made. Im going back to the cheapies.

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.

Amazing they all arrived the next day after ordering....to say the least I was impressed with amazon prime!!!

This thing is awesome. I have a few uneven pieces of wood flooring that Id been burning quite a bit of time slowly sanding down. I decided to try this out instead and in about 10 minutes Id managed to do what would have taken a few hours with the sander. That being said, be very careful since it removes a lot of material very quickly.

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.

Awesome grinding wheel did the job in quick time.quality Dewalt tools

I sculpt with metal, mainly found steel, and use flap discs in the finishing process often on very rough surfaces. These discs are workhorses, work rapidly and produce fine finishes
