3M 7000118255 Sanding Sheet 120 Grit Aluminum Oxide 211K

Product Description

The 3M 7000118255 is an aluminum oxide sanding sheet designed for dry abrasive finishing work across a range of trade and industrial applications. Built on a J-weight cloth backing, it offers flexibility and conformability for contoured or flat surfaces. Running at 120 grit, this sheet falls in the fine grade range, making it well suited for surface prep, stock removal finishing, and pre-coating smoothing. The aluminum oxide abrasive delivers consistent cut and durability across wood, metal, and composite materials. At 0.01 pounds per sheet, it is lightweight and easy to handle for extended use sessions.

This sanding sheet is used in dry sanding applications where a fine finish is required before painting, staining, or coating. The cloth backing with J-weight designation gives the sheet enough flexibility to work on irregular profiles while maintaining abrasive contact. Typical install scenarios include metal fabrication shops, woodworking facilities, general maintenance environments, and field finishing work performed by millwrights, pipefitters, or general contractors. It is sold individually but carries a minimum order quantity of 50 sheets per order.
