Merit Abrasives 08834173079 Psa Sanding Disc 80 Grit 15 in

Product Description

The MERIT ABRASIVES 08834173079 is a 15-inch pressure-sensitive adhesive (PSA) sanding disc designed for use with stationary disc sanders. Built on a flexible cloth backing and loaded with aluminum oxide abrasive, this disc delivers consistent stock removal at 80 grit across metal, wood, and composite surfaces. The black aluminum oxide grain is well-suited for medium-grade material removal tasks where surface prep consistency matters. At 0.5 pounds, it is lightweight and easy to handle during changeouts. No vacuum holes are included, making it a straightforward fit for solid platen stationary sanders.

This disc is intended for use on stationary disc sanders in both shop and light industrial environments. The PSA mount means installation requires no hardware — the adhesive backing bonds directly to the sanding platen. The 80-grit cut rate makes it appropriate for initial shaping, weld seam leveling, and surface preparation before finishing steps. Fabricators, metalworkers, and woodworkers in production or job-shop settings are the primary users of this disc size and grit combination.

Installation Notes

Power down and lock out the sander before removing the old disc and installing a new one. Peel the release liner from the adhesive backing and align the disc carefully to the platen center before pressing down, as repositioning after contact is limited. Ensure the platen surface is clean and free of adhesive residue from the previous disc for proper bond. This product should be installed and operated by personnel familiar with abrasive equipment safety practices.
