3M 7100199697 Stikita 321U Disc Roll 5 Inch 40 Grit

Product Description

The 3M 7100199697 is a Stikita 321U abrasive disc roll designed for automotive paint preparation and body repair work. It combines aluminum oxide mineral with a ceramic grain blend on a paper backing, delivering consistent cut across a range of sanding applications. The disc roll features an anti-loading coating that resists clogging from dust and debris, extending usable disc life. Adhesive-backed Stikita attachment allows fast disc changes without tools. At 5 inches in diameter and 40 grit, this roll suits aggressive material removal tasks in collision repair and surface prep workflows.

This abrasive disc roll is suited for automotive and body shop environments where technicians cycle through multiple grits during the paint preparation process. The 40-grit ceramic aluminum oxide construction handles rough shaping and stock removal on body filler, primers, and bare metal. The roll format allows individual discs to tear off one at a time without liners, reducing handling time during high-volume repair work. Body shop technicians and automotive refinishing professionals are the primary installers of this product.
