3M 7000118854 Abrasive Belt 100 Grit 4x24 in

Product Description

The 3M 7000118854 is a coated abrasive belt designed for dry grinding, blending, and finishing operations on metal, wood, and composite surfaces. Built on a heavy-duty X-weight cloth backing, it uses closed-coat aluminum oxide abrasive at 100 grit (fine grade) for consistent stock removal and smooth surface prep. The 341D series construction bonds abrasive grain tightly to the backing, supporting sustained performance through extended runs on stationary and portable belt sanders. HVAC and mechanical trade shops use this belt for deburring pipe ends, cleaning weld seams, and prepping metal surfaces before brazing or coating.

This belt measures 4 inches wide by 24 inches long and fits belt sanders and grinders accepting that standard size. It is suited for dry-only operation and is commonly found in fabrication, maintenance, and mechanical service environments. The fine 100-grit rating makes it appropriate for intermediate to finish-pass work where aggressive material removal is not required but surface condition matters before final treatment or inspection.

Key Features

• 100-grit aluminum oxide abrasive for fine-grade dry grinding and surface finishing
• Closed-coat construction maximizes abrasive coverage for consistent cut rate
• X-weight cloth backing provides strength and flexibility under load
• 341D series design supports use on both portable and stationary belt sanding equipment
• Dry-operation only — not rated for wet or coolant-assisted grinding

Compatibility

Designed as a direct-fit replacement belt for belt sanders and grinders accepting a 4-inch by 24-inch abrasive belt in dry-operation applications.

Installation Notes

Installation is performed by maintenance technicians, fabricators, or trade professionals servicing belt sanding equipment. Power down and lockout the sander before changing the belt. Confirm belt tracking direction matches the arrow printed on the belt backing before tensioning. Inspect the platen and idler roller for wear before mounting a new belt to avoid premature failure.
