3M 7100128758 Cubitron Ii 784F Abrasive Belt 80 Grit

Product Description

The 3M 7100128758 is a Cubitron II 784F cloth abrasive belt engineered for medium-pressure grinding and blending on metal surfaces. It measures 18 inches in length and 3/4 inch in width, running at 80 grit. The belt uses 3M Precision-Shaped Grain technology, which combines shaped ceramic mineral with premium aluminum oxide to deliver a faster, more consistent cut compared to conventional ceramic aluminum oxide belts. A YF-weight polyester backing provides moderate flexibility for conformability on both straight and contoured surfaces. The durable resin bond resists heat-related deterioration, and a built-in grinding aid cools the abrasive zone during work on heat-sensitive alloys. Licensed HVAC techs, metal fabricators, and industrial maintenance professionals install and run this belt in robotic and pressure-assisted grinding systems.

This belt is suited for wet and dry applications across a broad range of metal types and alloys. It is designed for medium-pressure grinding and blending workflows where consistent stock removal and extended belt life reduce changeout frequency and system downtime. The conformable backing makes it effective on both flat and contoured workpiece geometries, including weld blending and surface finishing operations in fabrication and manufacturing environments.

Key Features

• 3M Precision-Shaped Grain blend of shaped ceramic and premium aluminum oxide for faster, more consistent cut

Compatibility

Designed as an OEM-style replacement abrasive belt for medium-pressure belt grinding and blending machines that accept 18-inch by 3/4-inch abrasive belts.

Installation Notes

Belt installation should be performed by qualified personnel following the machine manufacturer's guidelines. Power down and lockout/tagout the grinder before removing or installing any abrasive belt. Inspect the contact wheel, platen, and belt tracking adjustment before mounting the belt. Verify belt tension and tracking alignment at low speed before returning the machine to full operation.
