3M 7100215956 Abrasive Disc Roll 320 Grit 5 Inch Ceramic Ao

Product Description

The 3M 7100215956 is a Stikita 321U abrasive disc roll designed for automotive paint preparation and body repair sanding. It combines a ceramic and aluminum oxide mineral blend on a paper backing to deliver consistent cut and finish across multiple stages of surface work. An anti-loading coating keeps the cutting surface clear of dust and debris, extending usable disc life. The adhesive-backed Stikita attachment system lets technicians swap discs quickly without liners. At 320 grit and 5 inches in diameter, this roll is sized for DA sanders and rotary tools common in auto body shops.

This disc roll is intended for automotive refinishing environments, covering paint preparation, featheredging, and body repair sanding applications. The 5-inch diameter fits standard dual-action and rotary sander pads equipped for adhesive-backed discs. The 320-grit rating makes it suitable for scuff sanding primer, blending clear coat edges, and final surface prep before topcoat application. Individual discs tear off one at a time from the roll without a liner, which reduces handling time during production work.

Installation Notes

Disc rolls of this type are installed by auto body technicians and detailing professionals. Before attaching a disc, confirm the sander pad is clean and free of debris to ensure full adhesive contact. Operate the sander within the speed range recommended by the tool manufacturer for adhesive-backed discs. Discard discs that show visible loading, tearing, or loss of cut rather than continuing use.
