Serious Grit 6" 49 Hole sanding discs are premium film-backed discs designed to fit all Festool ETS and RO 150 series random orbital sanders with Multi-Jetstream 2 backing pads.

We offer grits from 40 grit to 2000 grit for everything from rough shaping to fine finishing work.

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

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

Each box contains 50 sanding discs - except for 40 grit and 60 grit, which contain 25 discs per box.

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.

Our Secret Formula

We'll let you in on some secrets - here are 3 of the ingredients that make our discs so famous.

Film Construction

What does that mean? Well most discs adhere the abrasive grain to a backing made of paper. Ours use a polyester film backing which is usually reserved for the highest end professional discs due to the costs involved but we bring it to everyone.

Anti-Clog Coating

Our proprietary heat treated zinc stearate coating resists clogging so the abrasive surface stays cleaner and cuts more effectively for longer - especially on soft materials like paint, primer, softwoods, and drywall compound.

Premium Hook & Loop

We use an ultra-premium 70% nylon material for our hook & loop backing. This ensures a secure hold to your sander pad, reducing slippage and preventing discs from flying off during use - even under heavy pressure or at high RPMs.

Made To Last

Say goodbye to torn edges. Our discs are backed with a flexible polyester film that resists tearing, cracking, and edge breakdown—especially around hole patterns where paper often fails. That means fewer wasted discs and more time sanding.

Flawless Finish

The polyester film backing is perfectly flat and won’t wrinkle or deform under pressure. That creates a consistent surface that holds abrasive grain evenly across the disc—so you get a uniform scratch pattern and a smoother final finish with less effort.

Wet/Dry Ready

Paper backing swells and breaks down when exposed to water, but film stays stable. Our discs are built with a waterproof film layer that won’t warp, even in wet sanding or high-humidity environments—so you can sand confidently in any environment.
