Superior Abrasives A018263 Psa Disc 9 in 80 Grit

Product Description

The SUPERIOR ABRASIVES A018263 is a 9-inch pressure-sensitive adhesive (PSA) disc designed for aggressive stock removal on metal and non-metallic surfaces. It runs an 80-grit aluminum oxide abrasive on an X-weighted cloth backing, giving it the stiffness and durability needed for sustained grinding and blending passes. The PSA mounting style allows fast disc swaps on compatible platen grinders without tools. At 0.11 pounds per disc, it is lightweight without sacrificing cutting performance. This disc is a staple consumable for fabrication shops, weld prep, and surface conditioning work.

This disc is suited for use on platen grinders in both shop and light industrial settings. Approved material applications include alloy steel, ferrous metal, non-ferrous metal, stainless steel, and non-metallic materials, making it versatile across common fabrication tasks. The flexible cloth backing conforms slightly to workpiece contours, helping maintain consistent abrasive contact during finishing passes. It is a single-disc unit sold in a minimum order quantity of 25 discs, appropriate for regular production use where consumable volume matters.

Installation Notes

This disc is installed by a fabricator or abrasives technician onto a platen grinder equipped with a PSA-compatible pad. Before mounting, ensure the machine is powered off and the existing disc is fully removed and the pad surface is clean and free of adhesive residue. Do not exceed the 1,720 RPM maximum speed rating. Inspect the disc for damage before each use and replace immediately if delamination or tears are observed.
