3M 7000120353 Microfinishing Film Disc 268L 5 Inch Hook Loop

Product Description

The 3M 7000120353 is a coated abrasive microfinishing film disc designed for precise, uniform, close-tolerance surface finishing. This disc uses micron-graded aluminum oxide mineral resin-bonded to a 3 MIL high-strength polyester film backing. It operates at speeds up to 12000 RPM and measures 5 inches in diameter. The hook and loop attachment system allows fast disc changes and reuse on compatible random orbital and DA sanders. Finishing professionals and body technicians use this disc for defect repair, surface leveling, paint prep, and final finishing work requiring tight tolerance control.

This disc is suited for wet or dry applications in automotive refinishing, precision manufacturing, and surface preparation environments. The water-resistant polyester film backing holds up in wet sanding operations, while the micron-graded mineral delivers repeatable finish consistency across multiple passes. Color coding helps technicians identify grit levels quickly and reduces the risk of using the wrong disc in a multi-step finishing sequence.

Installation Notes

Installation and disc changes should be performed with the tool unpowered and disconnected from the air supply or electrical source.
