3M 7100115435 Cubitron Ii 947A Abrasive Belt 80 Grit

Product Description

The 3M 7100115435 is the Cubitron II 947A coated abrasive belt, built around 3M Precision-Shaped Grain technology that slices through metal rather than gouging or plowing like conventional abrasive grain. The result is faster material removal, cooler cutting temperatures, and longer belt life compared to standard ceramic abrasive belts. Measuring 18 inches in length and 3/4 inch in width with an 80 grit rating, this belt is engineered for low and medium pressure grinding and finishing applications. A grinding aid is incorporated into the construction to further reduce friction and heat at the contact point. Licensed trade fabricators, metalworkers, and finishing specialists are the primary installers and users of this belt.

This abrasive belt is optimized for use on stainless steel, mild steels, and aluminum. The X-weight poly-cotton backing provides the flexibility needed for contour work and surface blending on metal fabrication projects, pipe finishing, and weld seam removal. It is suited for both bench-mounted and portable belt grinder setups operating at low to medium contact pressure. Applications span light manufacturing, maintenance shops, and field metal finishing work.

Key Features

• Precision-Shaped Grain cuts faster and cooler than conventional ceramic abrasive belts
• Integrated grinding aid reduces friction and lowers heat buildup at the workpiece
• X-weight poly-cotton backing delivers flexibility for contour and surface applications
• 80 grit rating suited for aggressive stock removal with controlled surface finish
• Optimized for low and medium pressure operation on ferrous and non-ferrous metals
• Extended belt life compared to standard ceramic alternatives

Compatibility

Designed for use on stainless steel, mild steels, and aluminum in low and medium pressure belt grinding and finishing applications. Fits belt grinders accepting an 18 inch by 3/4 inch belt.

Installation Notes

Belt grinder installation should be performed with the machine powered off and unplugged before changing belts. Verify belt tension and tracking alignment before resuming operation. Use appropriate personal protective equipment including eye protection and gloves when handling abrasive belts and during grinding operations. Follow the grinder manufacturer guidelines for maximum belt speed ratings to avoid belt failure.
