3M 7100098196 Stikita 321U 6 in 600 Grit Abrasive Disc Roll

Product Description

The 3M 7100098196 is a Stikita 321U abrasive disc roll designed for automotive paint preparation and body repair work. Each roll combines aluminum oxide mineral with ceramic grain, giving the abrasive a balanced cut rate across a broad range of sanding tasks. The 600-grit rating targets fine finishing and surface leveling stages of a repair. An anti-loading coating keeps the cutting surface clear of dust and debris, extending usable disc life. The paper backing and Stikita adhesive system let technicians peel and attach individual discs without liners, keeping workflow moving on the shop floor.

This disc roll is suited for body shop technicians and automotive refinish professionals working through the paint preparation process. The 6-inch diameter fits standard dual-action and random-orbital sanders equipped for adhesive-backed discs. Applications include featheredging, scuff sanding, and fine surface prep before primer or topcoat application. The 600-grit ceramic AO blend handles both bare substrate and coated surface work at this stage of the repair cycle.

Compatibility

Designed for use with 6-inch dual-action and random-orbital sanders that accept adhesive-backed (PSA-style) disc attachments in automotive refinish and body repair applications.

Installation Notes

These discs are installed by automotive refinish technicians. Ensure the sander backing pad is clean and free of debris before attaching each disc to maintain proper adhesion and prevent premature release during use. Operate sanding equipment at manufacturer-recommended speeds for the grit and backing type. Inspect the disc for wear or loading before each pass and replace as needed to maintain consistent surface quality.
