What makes Serious Grit seriously good sandpaper?

  • Lasts Longer - the heat treated aluminum oxide grain is self-sharpening so you get an even finish throughout the life of the disc.
  • Won't Tear - rather than the typical paper material most sanding discs use, ours use a super strong film material that is both waterproof and very resistant to tearing.
  • Doesn't Clog - when your discs clog up with material, they lose their effectiveness quickly. Ours use a proprietary non-loading open coat zing stearate that sheds the dust before it has a chance to clog up.
  • Reusable - our hook and loop material is made from a more expensive 60% nylon blend which enables it to be removed and reapplied more times than the competition. This means no more discs flying off your sander and less money wasted.

Love the serious grit sanding discs


got these discs fast, and they fit my Festool. Perfect.

Good paper

Good sandpaper, seems to last longer on the higher grits.

Thanks William, glad you are liking them!


So far I really like using the sandpaper, it cuts through material quickly and doesn’t gum up or fill up like the paper I’ve been using. I love how durable it is! Will definitely be using Serious Grit on all my sanders from now on.
Hope you start making belts for handheld belt sanders 4”x24” and for my combo sander 6”x48” and 12” disks.
