3M 7100160972 Sanding Screen Discs 80 Grit 7 Inches

Product Description

The 3M 7100160972 is a silicon carbide sanding screen disc designed for final-stage wood finishing and inter-coat scuffing applications. The open mesh construction reduces loading, meaning the disc stays cleaner and cuts more consistently across its service life compared to solid-backing abrasives. At 7 inches in diameter with an 80-grit rating, this disc targets the removal of raised wood grain after initial sealer or finish coats, leaving a smooth, uniform surface ready for the next application. Finishing carpenters, floor refinishers, and millwork contractors reach for this disc when consistency between coats matters.

This disc is suited for residential and light commercial wood finishing work, including furniture, cabinetry, hardwood floors, and interior trim. The 80-grit rating makes it appropriate for scuffing between finish coats where aggressive material removal is not needed but surface uniformity is critical. The open mesh backing allows dust and debris to pass through rather than accumulate on the abrasive surface, extending usable life in high-volume finishing environments.

Key Features

• Silicon carbide abrasive bonded to open mesh for reduced loading and consistent cut
• 80-grit rating suited for final sanding stages and inter-coat scuffing
• 7-inch diameter fits standard disc sanders and random orbital tools accepting that size
• Open mesh construction extends disc life by allowing debris to clear the abrasive surface
• Designed specifically for raised-grain removal after sealer and finish coat application

Compatibility

Designed as an OEM-style replacement sanding disc for use with 7-inch disc sanders and finishing equipment accepting open-mesh screen discs in that diameter.

Installation Notes

Disc installation and replacement should be performed with the sander powered off and unplugged from its power source. Ensure the disc is seated flat and secured to the backing pad before operation to prevent uneven wear or disc separation. Operators should wear appropriate respiratory protection when sanding finish coats, as fine particulate from cured finishes may be hazardous. Follow local occupational safety guidelines for abrasive tool use in enclosed spaces.
