They are not as durable as the Blackstone brands I have used in the past. I hooked the edge of this sanding disc into a piece of 1/4" sheet steel and the disc lost the giant chuck of sanding sheets. From that point on, it fell out of balance and was never used, with little bits of sandpaper littering it for cleaning. Blackstone Brand Abrasive flap disc The sandpaper is stacked on top and is much more durable So far the Blackstone discs will wear out but continue to work just at a lower grit They break down much quicker I think it would take 20pcs so much so long to hold like a Blackstone grinding wheel. .
