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

Hard to beat dewalt products, I’m hard on grinding wheels and these are long lasting

Works well got the job done .

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.

Great grinding/sanding flap disk. Long wear.

I like these but the life span of good grinding seems to be short for the price paid. The benefit though is the ability to grind without grinding hard flat points into the material. With practice you can follow the natural contour of the metal you are grinding. Use these when you want to shape or clean off the surface; used the solid grinding wheels when you need to grind down to get the final shape before using these disks.

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.

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.

I love the quality of Dewalt tools, and I really love the amazing prices you can find them for through Amazon. Combine that with the free two day shipping that Amazon Prime membership provides, and these tools are a do-it-yourselfers dream. Any time I have a chore or project coming up, I check Amazon to see which Dewalt tools will do the job more efficiently. At these prices and with such fast shipping, it is always possible to have the right tool for any job.

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

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.
