3M 7000118346 Abrasive Shop Roll 240 Grit 1 Inch X 50 Yards

Product Description

The 3M 7000118346 is a utility cloth abrasive shop roll designed for dry sanding applications on metal and other surfaces. It uses aluminum oxide abrasive mineral, which cuts fast and maintains consistent performance through extended use. The J-weight cloth backing provides full flexibility, making it easy to wrap around contoured surfaces, shaped parts, and irregular profiles. At 240 grit (very fine), this roll produces a smooth, consistent finish suitable for finishing passes and surface prep. Closed coat construction keeps abrasive grain densely packed across the full surface for even material removal. HVAC fabricators, metal workers, and general trade technicians keep this roll format on hand for versatile shop use.

This abrasive shop roll is well suited for general-purpose dry sanding in fabrication shops, maintenance facilities, and trade service environments. The 1-inch width is a common size for detail work, edge sanding, and use with inline or mandrel-style sanding tools. At 50 yards per roll, it provides sufficient length for repeated cut-and-use applications. The 240 grit rating places it in the very fine finishing range, making it appropriate for final surface prep before coating, painting, or assembly on metal components.
