3M 7010326380 Abrasive Belt 100 Grit 3x21 Aluminum Oxide

Product Description

The 3M 7010326380 is a coated abrasive belt designed for dry stock removal and surface finishing on metal, wood, and composite materials. Built on an X-weight cloth backing, it carries 100-grit aluminum oxide abrasive in an open-coat density pattern. The open-coat layout reduces loading and extends belt life during aggressive material removal. At 3 inches wide and 21 inches long, this belt fits standard bench-top and portable belt sanders commonly used in fabrication shops, maintenance facilities, and light industrial settings. Technicians and tradespeople who need a consistent fine-grade cut on ferrous and non-ferrous surfaces reach for this configuration regularly.

This belt is suited for dry grinding and finishing operations where heat management and abrasive loading are concerns. The 340D series designation indicates a production-grade cloth construction capable of handling the tension and flex demands of high-cycle power sanding equipment. Typical applications include deburring, weld seam blending, and surface prep on structural steel, aluminum stock, and hardwood components. It is sold individually, making it practical for spot replacement or trial use before committing to larger quantities.

Installation Notes

Always power down and unplug the sander before changing the belt. Confirm belt tracking alignment after installation and before full-speed operation. Inspect the platen and drive rollers for wear or debris that could cause uneven belt contact or premature failure.
