3M 7000120371 Microfinishing Film Disc 268L 5 Inch Ao

Product Description

The 3M 7000120371 is a coated abrasive microfinishing film disc engineered for precise, close-tolerance surface finishing in professional finishing and surface prep applications. Built on a 3 mil, water-resistant polyester film backing, the disc uses micron-graded aluminum oxide mineral resin-bonded for consistent cut and durability across both wet and dry use. Rated to 12000 RPM and measuring 5 inches in diameter, this disc mounts via hook and loop attachment for fast swaps and repeatable positioning. It is designed for defect repair, paint leveling, and final finishing work where uniform surface texture is required.

This disc is suited to body shop technicians, automotive finishing professionals, and industrial surface prep specialists working with tight-tolerance finish requirements. Typical applications include paint defect removal, surface leveling before clear coat, and final finishing passes where consistent scratch patterns are critical. The color-coded design reduces selection errors when multiple grits are in use at the same workstation. Both wet and dry working conditions are supported by the water-resistant film backing.

Installation Notes

This disc is installed and serviced by finishing technicians using random orbital or disc sanders equipped with 5 inch hook and loop backing pads. Ensure the tool is powered off and unplugged before mounting or removing the disc. Confirm the tool RPM rating does not exceed the disc maximum of 12000 RPM before operation. Inspect the backing pad for contamination or wear that could affect disc adhesion and finish consistency.
