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

This flap disc is the real deal. DEWALT slapped some zirconia grit on a wheel and basically handed you a surface-smoothing weapon of mass reduction. Whether you’re cleaning up welds, smoothing edges, or shaving down that "oops" cut you swore was straight—this thing handles it like a champ. Durability? Let’s just say it outlasted my attention span and my playlist. It cuts smooth, runs cool, and doesn’t shred itself to pieces halfway through a job like those bargain-bin brands. Put it on your grinder and let it work its magic. You’ll be turning rough steel into buttered toast in no time.

I used this along with an angle grinder to sharpen my lawn mower blades. It did a great job and I did not notice any damage to the disc after the job was done. I anticipate being able to reuse this disc for many more blade sharpenings. It was able to successfully sharpen the blade and I knew it was working from all the sparks that were generated at the time. I think this is a great value.

These work great. They don't damage wood and really strip the varnish without gumming up

The product is great but why add special instructions for the delivery driver if they are not going to follow them. Leave on porch real simple. Not at mail box out at the road.

Sharped and durable

Purchased a 40 and 80 grit for a fiber glass repair on my boat. Quickly realized how versatile they are. Used to sharpen mower blades, sand wood and fiberglass, and for rust removal. These are much faster and thorough than wire brushes for rust and paint removal..not to mention safer. Were also almost half the price of Lowes and Home Depot. I use air and a stainless brush to clean. Highly recommend.

Good tool

Excellent quality and durability The price was a bargain for what you can get out of this grinner blade/disc
