Réponse reçue de Saint Gobin propriétaire de Norton.
Thank you for contacting Norton Saint-Gobain Abrasives. How long have you had the belts before you used them and that may explain why they might have broke so fast. If you had them for a long time and have not used them and they sit around then they can be exposed to different temperatures which can brittle the tape on the belts. If you have not had the belts for a while then you can try and take them back to the place or Distributor you bought them from and tell them what happened.
