DetailsOur cooling back up pads for fibre discs will get the job done. The pads give maximum support to your fibre discs while the cooling design increases air flow between the disc and pad. From the lightest application to the heaviest grinding our pads allow you to get the most from your abrasive discs. The pads are furnished for the standard 5/8-11 spindle. Disc pad nuts and spanner wrenches are sold seperately.
