The 3M 52" x 75" 120 Grit Coated Aluminum Oxide Fine Abrasive Belt is engineered for reliable sanding performance in demanding applications. The aluminum oxide abrasive delivers consistent cutting action and extended abrasive life. Its open coat construction improves efficiency on wood surfaces while reducing loading. A heavy duty cloth backing provides durability for high-production environments, and the washable backing supports repeated use on high-loading substrates such as pine. The resin bond construction withstands elevated heat and pressure for consistent performance during extended operations.
