3M Company BELT3X211PK80 Abrasive Sanding Belt 80 Grit

Product Description

The 3M COMPANY BELT3X211PK80 is an 80-grit abrasive sanding belt measuring 3 x 21 inches, sold in a 10-pack, and built for portable belt sanders used in woodworking, metal fabrication, and surface prep applications. The belt combines Cubitron abrasive grain with premium aluminum oxide blended minerals on a heavy Y-weight cloth backing. A film splice construction allows the belt to run bi-directionally, extending usable life and reducing the need for frequent belt changes. This is a working trade consumable suited for rapid material removal on a wide range of substrates.

This sanding belt is designed for use with portable handheld belt sanding tools common in carpentry, finish work, metal prep, and general construction environments. The 80-grit cut rate makes it appropriate for aggressive stock removal and leveling passes before transitioning to finer grits. The Y-weight cloth backing holds up under the heat and pressure generated during continuous power sanding, making it a reliable choice for production-rate work and job-site use.
