3M 7100048870 Scotch-brite 6 Inch Non-woven Abrasive Disc

Product Description

The 3M 7100048870 is a Scotch-Brite PO-DC non-woven abrasive disc designed for cleaning, scuffing, surface finishing, and light paint removal on metals and plastics. Built on a flexible nylon open-web construction, the disc integrates very fine grade aluminum oxide (AO) mineral throughout the fiber matrix, so the abrasive continuously refreshes as the disc wears. Rated to 12000 RPM and sized at 6 inches in diameter, it is a direct replacement for steel wool, wire brushes, and sandpaper in surface preparation workflows. Licensed tradespeople and surface finishing technicians reach for this disc when a consistent, controllable cut is needed without aggressive material removal.

This disc suits a wide range of surface preparation tasks in HVAC, light fabrication, plumbing, electrical panel work, and general metalworking. It performs on ferrous and non-ferrous metals as well as plastics, making it useful for deburring, oxide removal, scuff-sanding before primer, and final blending passes. The open-web structure allows the disc to be used either wet or dry and rinsed for repeated use, extending service life in field and shop settings alike.

Key Features

• Very fine grade aluminum oxide abrasive for efficient cleaning and controlled finishing
• Flexible open-web nylon fibers conform to contoured and irregular surfaces
• Resists tearing, loading, and rust for extended service life
• Compatible with wet or dry use and can be rinsed and reused
• Replaces steel wool, wire brushes, and sandpaper in most surface prep applications
• 6 inch diameter fits standard disc backups rated to 12000 RPM

Compatibility

Designed as an OEM-style drop-in for standard 6 inch disc backup pads used in surface preparation, cleaning, and finishing applications on metals and plastics.

Installation Notes

Mount this disc only on a backup pad and tool rated for a minimum of 12000 RPM. Inspect the disc for tears or degradation before each use and remove it from service if the fiber matrix is damaged. When used for surface prep on energized electrical components or live HVAC systems, de-energize and lock out equipment per NFPA 70E or applicable site safety procedures before beginning work. Rinse with clean water after wet use and allow to dry fully before storage.
