Sav-A-Disc Phenolic Plates
Have you tried Sav-A-Disc?
Sav-A-Disc is a patented grinder backing plate and grinding system that significantly increases abrasive disc life and improves the quality of any surface preparation or finishing project.
Sav-A-Disc Operation – The unique ribbed construction of the plate puts the top and the secondary grit layers of the abrasive disc to work. Because the plate rotates freely, the abrasive disc is constantly changing its position relative to the ribs of the plate. Each grain on the disc is forced to lie on an angle on the ribs of the plate. This action continually unloads the disc and re-sharpens the grain. ( 7″ STANDARD SET SHOWN )
