3M 7100065092 Microfinishing Film Disc 268L 3 Inch Ao

Product Description

The 3M 7100065092 is a coated microfinishing film disc in the 268L series, designed for precision surface finishing in trade and industrial applications. Aluminum oxide mineral is resin-bonded to a 3 MIL high-strength polyester film backing, producing a fast-cutting disc capable of consistent, close-tolerance finishes. The disc measures 3 inches in diameter with a 0.87-inch arbor opening and mounts via a hook-and-loop interface for quick attachment and removal. It is suited for defect repair, leveling, paint prep, and final finishing work where uniformity and repeatability matter.

This disc is used in automotive refinishing, aerospace surface prep, metal fabrication, and woodworking where tight tolerances and repeatable results are required. The water-resistant polyester film backing supports both wet and dry use, making it adaptable to a range of shop and field environments. Technicians and finishing specialists working with random orbital or angle tools will find this disc fits standard hook-and-loop backup pads sized for 3-inch discs.

Key Features

Compatibility

Designed for use with 3-inch hook-and-loop backup pads on random orbital sanders, angle grinders, and similar pneumatic or electric finishing tools.

Installation Notes

Mounting and removal require no tools — press the disc firmly onto a compatible hook-and-loop backup pad to seat it fully before operating. Inspect the backup pad surface before each use to ensure hooks are intact and free of debris, which affects disc adhesion during operation. Disconnect or power down the tool before changing discs. Follow applicable shop safety protocols and any site-specific PPE requirements when performing surface prep or finishing operations.
