3M™ 364UZ | 54 inch X 103 inch P120 grit | Paper Belt 5 per box


5 per box

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.
