Standard Abrasives PSA A/O Disc 700778 3" x NH 320 Grit

Made with aluminum oxide mineral and adhered to an X-weight cloth backing, Standard Abrasives PSA Aluminum Oxide Disc is good for light-duty blending, finishing and polishing on ferrous and non-ferrous materials.

Great for Light-Duty Blending, Finishing and Polishing The X-weight cloth backing on Standard Abrasives PSA Aluminum Oxide Disc is durable and heavy, further enhancing the support the abrasive receives from the holder pad. This durability is what makes PSA Aluminum Oxide Disc a great match for light-duty blending, finishing and polishing on edges, extrusions and contours – it tends not to deflect on these irregular surfaces.
