20" Discs 100 and 36 Grits
These discs are perfect for bench-mounted sanders or other tools with a 20 inch PSA plate.
They are constructed on heavyweight cloth backing, with a strong PSA (pressure sensitive adhesive - stronger than Stikit) that will stand up to the high temperatures encountered in heavy coarse grit sanding.
These discs are available with both premium (700) and economy (300) series abrasives:
These 348D economy discs are constructed using select aluminum oxide abrasives on a rigid, heavy, D-weight cloth backing.
The 777F discs perform dramatically better than the 348D economy discs.
