3M 7100189666 Scotch-brite Cf-dc Non-woven Disc 5 Inch

Product Description

The 3M 7100189666 is a Scotch-Brite CF-DC Clean and Finish Disc built for surface blending, cleaning, and polishing across a wide range of materials. The disc combines a conformable non-woven web with aluminum oxide abrasive mineral to produce consistent, uniform finishes without undercutting or damaging the base material. At 5 inches in diameter and rated Very Fine grit, it is well suited for light stock removal, surface prep, and finish work on aluminum, stainless steel, plastics, wood, and fiberglass. Trade professionals use these discs where controlled, repeatable surface conditioning is required.

This disc is designed for use in fabrication shops, HVAC sheet metal work, plumbing rough-in prep, and general surface conditioning tasks where a fine, consistent finish is needed on formed or contoured parts. The open web construction resists loading, making it effective on materials that tend to clog conventional abrasive products. It attaches to a random orbital sander via a Hookit backup pad, allowing technicians to cover larger surface areas and increase cut rate compared to hand-applied finishing pads.

Installation Notes

Installation and use should follow standard abrasive safety practices. Ensure the sander is powered off and unplugged before mounting or removing the disc.
