The 3Mâ„¢ Hookitâ„¢ Regaliteâ„¢ Floor Sanding Disc (SKU 7100187100, Catalog No. FSD-80-6X6H) is a 6-inch, 80-grit abrasive disc designed for aggressive material removal on bare wood and non-gummy finishes. Featuring a durable paper backing and purple Regaliteâ„¢ synthetic mineral, these precut discs cut faster, run cooler, and last longer than conventional abrasives, significantly boosting productivity. The disc utilizes a 6-hole pattern for effective dust extraction when paired with compatible vacuum systems and attaches via a standard Hookitâ„¢ (hook-and-loop) system to most 6-inch floor edgers.
