Why do you need to upgrade my Random Orbital Sander to a heavy duty hook & loop system? 

  • The hook on most sanders sold today, is lightweight and not designed to hold a carbide sanding disc. 
  • Upgrading the hook on the sander, not only creates a strong bond for the DuraGRIT carbide sanding disc but also greatly improves the adhesion of ordinary disposable discs. 
  • (Please note the vacuum hole pattern is compatible with most 5" diameter sanders with a 5 or 8 vacuum hole pattern, but not Festool® orbital sanders)


  1. First step: Grind the existing hooks off your sander platen by running the bare platen on a sheet of 80 grit sandpaper taped to the bench 
  2. Make sure all hooks are gone and the platen is smooth 
  3. Clean with rubbing alcohol and let air dry 
  4. Before installing the black hook pad, check the platen is securely fastened to the sander motor 
  5. Remove all 8 vacuum hole plugs from the black hook pad and carefully align the pad with sander vacuum holes. 
  6. Holding the pad in position, peel half of the hook pad liner, attach and then remove the other half, smoothing the pad into position 
  7. To secure the adhesive, plug in the sander and run against the palm of your hand. 
  8. Next step is to trim the excess pad close to the sander platen. 
  9. Once the black pad is applied to the sander, you can now attach the heavy duty white loop pad to the back of your DuraDISC. 
  10. As with the black hook pad, remove all 8 vacuum hole plugs and align the pad to the edge of the disc. 
  11. Lift one half of the loop pad and peel the adhesive liner and smooth into place. 
  12. Then remove the other half of the liner, let it fall into place and smooth the whole pad flat. 
  13. You are now ready to attach the DuraDISC to your random orbital sander. 
  14. Place the carbide side of the disc against the sander platen and establish the overhang on your brand of sander. 
  15. Then place the disc carbide side down on the bench, and carefully align the sander to the disc, leaving the degree of overhang established in the previous step. 
  16. Now you are all set to get sanding. 
  17. Remember that to increase the life of the white loop pad, never run the sander when it is off the work surface or in free air. 
  18. Using a wide blade putty knife or spatula to remove the disc for grit grade changes, or cleaning, will help preserve the integrity of the loop pad and will keep the DuraDISC flat. 
  19. When it is eventually necessary to replace the white loop pad, two packs are sold at https://duragrit.com/DL5 
  20. CONGRATULATIONS! You are now all set.  Happy Sanding!
