3M 7100161092 Sanding Screen Discs 7 in 100 Grit

Product Description

The 3M 7100161092 is a sanding screen disc designed for finish sanding and scuffing between coats in wood finishing applications. Built with silicon carbide abrasive bonded to an open mesh backing, these discs resist loading better than closed-coat abrasives. The 7-inch diameter and 100-grit cut rating make them well suited for the final sanding stage, where removing raised wood grain without cutting too aggressively is the goal. The open mesh construction promotes consistent abrasive action across the disc face and extends usable life compared to standard sanding sheets.

These discs are used primarily in wood finishing workflows, including furniture production, cabinetry, and flooring prep. They are most effective in the final pre-finish sanding pass to knock down raised grain after a first wash coat or water-based finish application, and for scuffing between successive finish coats to promote adhesion. Finishing carpenters, cabinet makers, and wood floor technicians are the typical end users.
