3M 7100216686 Abrasive Disc Roll 240 Grit 6 Inch Ceramic Ao

Product Description

The 3M 7100216686 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 to deliver consistent cutting performance across a range of sanding tasks. The disc roll features an anti-loading coating that resists clogging from dust and debris, extending usable disc life between changes. Individual discs tear off one at a time without liners, and the Stikita pressure-sensitive adhesive backing allows fast, clean attachment and removal from orbital and random-orbit sanding tools. This roll is a practical shop supply for body technicians and auto refinish professionals.

This disc roll is suited for automotive bodywork environments where multiple stages of surface preparation are required, including bare metal work, primer sanding, and finish prep. At 240 grit with a 6-inch diameter, it targets fine-to-medium stock removal and surface smoothing in the final stages of paint prep. The roll format reduces downtime during high-volume sanding jobs by keeping a continuous supply of fresh discs at hand without the need for individual disc liners or backing sheets.
