Merit Abrasives 08834173109 Psa Sanding Disc 16 in 80 Grit

Product Description

The MERIT ABRASIVES 08834173109 is a 16-inch pressure-sensitive adhesive (PSA) sanding disc designed for use on stationary disc sanders. It features an aluminum oxide abrasive in 80 grit, a medium-grade cut suited for stock removal and surface prep on wood, metal, and composites. The cloth backing provides flexibility and durability under continuous machine operation. At 0.5 pounds, this disc mounts quickly to PSA-compatible platens without fasteners or clamps, making changeovers fast during production sanding tasks. No vacuum holes are included, so it is intended for solid-platen sanders rather than dust-extraction setups. This disc is part of the PSAAO series and is sold individually.

This disc is used on stationary disc sanders in woodworking shops, metal fabrication facilities, and general manufacturing environments. The 80-grit aluminum oxide cut handles initial shaping, weld seam blending, and surface leveling passes before finer grits are applied. The flexible cloth backing conforms slightly to workpiece contours, reducing gouging on curved or irregular surfaces. It is typically installed and changed out by machine operators or shop technicians maintaining production sanding equipment.

Installation Notes

Power down and lockout the sanding machine before removing or installing any disc. Clean the platen surface of adhesive residue and debris before applying the new disc to ensure full contact and even backing adhesion. Press the disc firmly from the center outward to eliminate air pockets. Inspect the disc for edge lifting before resuming operation.
