3M 7100057403 Abrasive Disc Roll 5 Inch P180 Grit Aluminum Oxide

Product Description

The 3M 7100057403 is a Stikit 216U coated abrasive disc roll designed for fast attachment to a Stikit backup pad, delivering consistent material removal in finishing applications. Each disc features an aluminum oxide mineral on an A-weight light paper backing with an open coat construction. The load-resistant coating helps prevent premature glazing of the abrasive surface, extending usable life between disc changes. This roll format eliminates individual disc liners, keeping workflow moving on sanding stations in fabrication shops, body shops, and light manufacturing environments. Discs are rated at P180 grit, positioning them for fine stock removal and surface prep prior to finishing.

This disc roll is suited for finishing operations on wood, metal, and composite surfaces where a P180 grit cut is appropriate. The Stikit pressure-sensitive adhesive backing allows quick disc swaps on compatible Stikit backup pads, which are sold separately. The roll format is practical for high-volume sanding tasks where technicians need to cycle through multiple discs during a single job. Typical users include body shop technicians, woodworkers, and general fabrication professionals who prioritize productivity during surface preparation and finish-sanding stages.

Installation Notes

Mount the disc to a clean, compatible Stikit backup pad by pressing firmly and evenly across the adhesive face before operation. Ensure the pad surface is free of debris or residual adhesive before applying a fresh disc to maintain secure contact. Operate at speeds within the rated limits of the backup pad being used. Wear appropriate PPE including eye protection and respiratory protection when sanding.
