3M™ Paper Belt 346UZ is constructed with a premium aluminum oxide mineral. It is an open coat construction for loading resistance and is coated on an F-weight paper backing to efficiently sand and finish. F-weight is one of the heaviest, most rigid paper backings available and will achieve finer finishes than cloth backed belts in the same grade.
Anti-static treatment helps manage dust and loading. F-weight heavy paper backing provides durability and smooth operation in either direction. Open coat provides fast stock removal. Premium aluminum oxide mineral provides aggressive cut and long abrasive life. Sine wave splice prevents hinging in splice area, resists fatigue, and minimizes chatter marks
