The 3M 7100123057 is a Hookit Purple Finishing Film Abrasive Disc from the 260L series, designed for fine finishing work on automotive clear coat and painted surfaces. Built with aluminum oxide abrasive on a flexible film backing, this disc cuts consistently while resisting loading, meaning fewer disc changes and less downtime during surface prep. The updated coating formulation targets surface defects and significantly reduces pigtailing, which is a common cause of rework in finish-grade sanding. At P2000 grit, it leaves a fine, uniform scratch pattern that polishes out quickly. Professional auto body technicians and paint finishing specialists are the primary users of this disc.
This disc is suited for fine finishing applications on clear coat, base coat, and primer surfaces in professional auto body and collision repair environments. It performs well in both wet and dry finishing stages where a consistent, pigtail-free scratch pattern is required before polishing. The 6 inch diameter fits standard 6 inch Hookit backup pads. Multiple hole pattern configurations are available within the 260L product line for improved dust extraction when used with a vacuum or sander dust collection system.
Designed for use with 6 inch Hookit backup pads and compatible random orbital or dual-action sanders that accept the Hookit attachment system.
Installation and disc changes are performed by hand with no tools required when using a Hookit-compatible backup pad. Ensure the sander is powered off and disconnected before changing discs. Align the disc squarely on the backup pad and press firmly to seat the attachment. When using with dust extraction, match the disc hole pattern to the backup pad hole pattern for optimal airflow.
