3M 7100122769 Cubitron Ii 784F Abrasive Belt 60 Grit

Product Description

The 3M 7100122769 is a Cubitron II 784F cloth abrasive belt designed for medium-pressure grinding and blending on metal surfaces. It measures 25 inches long by 1/2 inch wide and cuts at 60 grit. The belt uses 3M Precision-Shaped Grain technology, a blend of shaped ceramic and premium aluminum oxide minerals, to deliver a faster and more consistent cut than conventional ceramic aluminum oxide belts. A durable resin bond resists heat-induced deterioration, and the YF-weight polyester backing is waterproof, making the belt suitable for both wet and dry applications. Licensed HVAC, metal fabrication, and industrial maintenance technicians rely on this belt for high-throughput grinding and finishing work.

This belt is built for medium-pressure grinding and blending on all metals, including heat-sensitive alloys where the integrated grinding aid helps control abrasive process temperatures. The moderately flexible backing conforms to both straight and contoured surfaces, making it effective in robotic, pressure-assisted, and hand-held applications. Its extended service life reduces changeouts and minimizes downtime in production environments where belt consumption directly affects throughput.

Key Features

• 3M Precision-Shaped Grain blend of shaped ceramic and premium aluminum oxide for faster, more consistent cutting than conventional ceramic aluminum oxide belts
• Grinding aid cools the abrasive process, protecting heat-sensitive alloys during grinding
• Waterproof YF-weight polyester backing rated for Grades 36-80, supports both wet and dry use on all metals
• Durable resin bond resists heat deterioration to extend belt service life
• Moderately flexible backing conforms to straight and contoured surfaces
• Reduces changeouts and downtime in robotic and pressure-assisted applications

Compatibility

Designed for medium-pressure grinding and blending applications on all metals using belt-type abrasive tools that accept a 25-inch by 1/2-inch belt.

Installation Notes

Belt installation and replacement should be performed by qualified personnel following the tool manufacturer's guidelines and applicable workplace safety standards. Power down and lock out the grinder or belt tool before changing belts. Inspect the contact wheel, platens, and tracking adjustment before mounting the belt to ensure proper alignment and tension. Always wear appropriate PPE including eye protection and gloves when handling and operating abrasive belts.
