3M 7100199702 Abrasive Disc Roll 5 Inch 220 Grit Ceramic Ao

Product Description

The 3M 7100199702 is a Stikita 321U abrasive disc roll engineered for automotive paint preparation and body repair sanding. Each roll combines a premium aluminum oxide mineral base blended with ceramic grain to maintain consistent cut rate across a wide range of sanding stages. The 220-grit rating targets final preparation passes where surface finish quality matters. An anti-loading coating keeps the cutting surface clear of dust and debris, extending usable disc life. Discs are adhesive-backed for fast Stikita attachment and tear off one at a time without liners, reducing changeover time on the shop floor. Licensed automotive technicians and body shop professionals are the primary installers.

This disc roll is suited for sanding primer, filler, and finish coats during automotive body repair and paint preparation workflows. The 5-inch diameter fits standard dual-action and random orbital sanders equipped for Stikita or PSA-compatible backup pads. The 220-grit ceramic AO combination makes this roll appropriate for intermediate-to-final sanding passes on both bare substrates and coated surfaces. Sold in roll form, discs are dispensed individually as needed, reducing waste and keeping unused discs protected until use.

Installation Notes

Automotive body technicians should confirm the backup pad is clean and free of debris before attaching each disc to ensure full adhesive contact. Power down the sander before changing discs. Operate within the RPM rating of the backup pad and sander to avoid disc separation. Wear appropriate respiratory protection when sanding coated surfaces per applicable shop safety standards.
