DEWALT Flap Disc, Zirconia, 4-1/2-Inch x 7/8-Inch, 80-Grit (DW8309)

Good wheels, have lasted well and perform well

Have only used once and they do a good job sharpening mower blades.

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.

Funciona muy bien, buena fabricación por el precio correcto y materiales de primera, llegó rápido y bien empacado.

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.
