3M 7100180141 Abrasive Belt 320 Grit 91x1 Inch Aluminum Oxide

Product Description

The 3M 7100180141 is a closed-coat aluminum oxide abrasive belt designed for general metalworking applications. At 91 inches long and 1 inch wide, this 320-grit belt runs on compatible belt sanders and grinders used in metal finishing, surface blending, and finish refinement. The flexible cloth backing allows the belt to conform to workpiece contours while maintaining consistent abrasive contact. Aluminum oxide mineral delivers fast cutting action and holds up well across repeated passes on ferrous and non-ferrous metal surfaces. Installed by metalworkers, fabricators, and finishing technicians in shop and field environments.

This belt is suited for dry sanding operations in general metal fabrication, repair, and surface preparation. The 320-grit rating places it in the fine-finishing range, making it appropriate for blending welds, smoothing surface defects, and refining metal finishes prior to coating or polishing. The glue bond construction supports uniform material removal and consistent scratch patterns in dry applications. It is sold individually and sized for machines that accept a 91-inch by 1-inch belt.

Key Features

• Aluminum oxide abrasive mineral cuts fast and performs reliably on metal surfaces
• Closed-coat construction delivers a consistent, fine scratch pattern across the workpiece
• Flexible cloth backing conforms to surface contours for general-purpose dry sanding
• Glue bond supports uniform finishes in dry sanding applications
• 320 grit for fine finishing, blending, and pre-coat surface refinement
• 91 inch length by 1 inch width fits standard belt sander configurations

Compatibility

Designed for use on belt sanders and grinders accepting a 91-inch by 1-inch abrasive belt. Suitable for general metalworking, metal finish repair, and surface blending on ferrous and non-ferrous metals in dry sanding conditions.

Installation Notes

Install and replace abrasive belts with the machine fully powered off and unplugged. Verify the belt tracking direction arrow aligns with the machine drive direction before operating. Inspect the belt for tears or delamination prior to each use and replace if damaged. Use appropriate respiratory and eye protection when sanding metal surfaces.
