3M 7100098251 Adhesive Back Sanding Sheet 220 Grit

Product Description

The 3M 7100098251 is an adhesive-back sanding sheet roll designed for precision surface finishing in trade and industrial applications. Constructed with a ceramic aluminum oxide abrasive on a C-weight paper backing, this sheet delivers consistent cut and durability across a range of finishing tasks. At 220 grit, it is suited for fine sanding passes where surface smoothness is the priority. The roll measures 2.75 inches wide by 30 yards long, providing ample material for extended use before replacement. The pressure-sensitive adhesive backing allows the sheet to mount directly to compatible sanding tools and blocks without additional fasteners.

This sanding sheet roll is used in woodworking, metal fabrication, automotive body finishing, and general surface preparation where a fine abrasive is required. The 2.75-inch width fits standard narrow-format sanding tools and hand blocks commonly used by finish carpenters, auto body technicians, and industrial maintenance trades. The 30-yard roll length suits production environments or high-volume finishing work where frequent media changes reduce efficiency. The blue-colored sheet aids in visual identification during tool changes.

Installation Notes

Clean and dry the sanding block or tool pad surface before applying the adhesive-back sheet to ensure proper adhesion. Align the sheet squarely to the pad before pressing down to avoid repositioning, as repeated peeling can reduce adhesive effectiveness. Disconnect or power down any pneumatic or electric sanding tool before mounting or removing abrasive media. Dispose of spent abrasive sheets in accordance with local waste regulations, particularly when used on materials that generate hazardous dust.
