Grinder Sanding Discs

Our Grinder Sanding Discs are resin-fibre abrasive discs for use with angle grinders, designed for aggressive material removal on GRP, fibreglass, composites, and similar hard surfaces where a random orbital sander would be too slow or impractical. Ideal for removing old laminate, levelling large high spots, and initial surface preparation on larger repair areas.

Always use with the appropriate backing pad for your grinder and select the correct grit for the task - coarser grits for rapid material removal, finer grits for surface preparation before switching to orbital discs for the finishing stages. For hook & loop orbital sanding discs, see our Indasa Rhynogrip and Mirka Abranet disc ranges in the Sanding Discs section. Order online today with fast delivery from CFS Fibreglass.
