3M 7100098194 Stikita 321U Disc Roll 6 Inch 400 Grit

Product Description

The 3M 7100098194 is a Stikita 321U abrasive disc roll engineered for automotive paint preparation and body repair sanding. The abrasive layer combines premium aluminum oxide mineral with ceramic grain 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 disc life between changes. The Stikita pressure-sensitive adhesive backing allows fast disc attachment and removal without liners. Discs tear off one at a time from the roll, reducing handling time and material waste. Licensed HVAC technicians, auto body technicians, and professional painters are the primary installers of this consumable.

This disc roll is suited for automotive body repair shops and refinishing facilities handling paint preparation, primer sanding, and surface leveling. The 6-inch diameter and 400 grit rating make it appropriate for fine finishing and final prep work before sealer or topcoat application. The ceramic aluminum oxide blend maintains an aggressive cut even at finer grit levels, supporting throughput on high-volume repair operations. The roll format minimizes downtime during disc changes on pneumatic or electric random orbital sanders.
