5" 9 Hole Hook & Loop Sanding Discs - Compatible with Festool Sanders


Serious Grit 5" 9 Hole sanding discs are premium film-backed discs designed to fit all Festool ETS and RO 125 series random orbital sanders. We offer grits from 40 grit to 2000 grit for everything from rough shaping to fine finishing work. 

Each box contains 50 sanding discs, except for the 40 grit and 60 grit boxes, which contain 25 discs each.

Mixed grit box includes 10 discs of each - 80, 120, 150, 180, and 220 grit.

High Grit box includes 10 discs of each - 320, 400, 600, 800, and 1000 grit.

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.

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.

You'll never go back

Best sandpaper I've ever used. Ordered on Monday received it on Friday. A box of 80 grit lasts me over a month in my shop


I really like these sanding disks. Long life and hardly any grit sluffoff.

60 and 80 grit discs

I think the sandpaper is excellent quality but I'm afraid I won't be able to use them again on my Festools sanders. They seem to wear out the pads prematurely, not sure why, but I think it's because the hooks are not an exact fit and are therefore causing some friction which in turn wears out the loops. Any advice or suggestions would be appreciated.
