Get the most from your abrasive discs with our tough 3M™ Fibre Disc Backup Pad. Our hard rubber pads provide firm, consistent support for 3M fibre discs on right angle and other sanding and grinding tools. They are compatible with a wide range of 3M face plates – simply choose the ideal density for your job. The pads work with the vulcanized fibre backing on the abrasive disc, helping it to conform to the surface for a smooth consistent finish during grinding and sanding. They reduce the vibration and chunking that degrades discs and help to ensure that the ceramic mineral abrasive on the fibre disc will continually self-fracture as designed – instead of breaking off in unused chunks. Our 7/8” diameter centre hole mount attaches firmly to grinding and sanding tools using a disc retainer nut*. Using our fibre disc back-up pad helps you get the most from each automotive body finishing application, and from your entire automotive body operation. *Sold separately
