3M™ Paper Belt 466UZ, P400 F-weight, 52 in x 128 in, Sine-lok, Full-flex

3M™ Paper Belt 466UZ is a smooth running belt constructed with silicon carbide mineral, bonded to an F-weight paper backing. The semi-closed coat construction efficiently sands and finishes flat surfaces in woodworking applications. F-weight is one of the heaviest, most durable paper backings available and will achieve finer finishes than cloth backed belts in the same grade.
