3M 7000028098 Psa Disc 5 in 100 Grit Aluminum Oxide 100 Pack

Product Description

The 3M 7000028098 is a pressure-sensitive adhesive (PSA) abrasive disc designed for material removal, surface preparation, and finishing work. The disc measures 5 inches in diameter and features 100-grit aluminum oxide abrasive, placing it in the fine grade category. A C-weight paper backing provides flexibility during use, making it well-suited for contour sanding and flat surface work. Each roll contains 100 discs. These discs are installed and used by trades professionals and finishing technicians requiring consistent, repeatable stock removal on wood, metal, and composite surfaces.

The 3M 7000028098 PSA disc is designed for use with random orbital sanders in production and shop environments. The pressure-sensitive adhesive backing allows fast disc changes without hook-and-loop hardware. Typical applications include furniture finishing, cabinet shop work, automotive body prep, and general metalworking surface conditioning. The yellow disc color aids in visual identification during high-volume use. No vacuum holes are included, making this disc appropriate for use on non-vac platens.
