3M 7100119302 Cubitron Ii 784F Abrasive Belt 80 Grit

Product Description

The 3M 7100119302 is the Cubitron II 784F cloth abrasive belt, engineered for medium-pressure grinding and blending on metal surfaces. It uses 3M Precision-Shaped Grain, a proprietary blend of shaped ceramic and premium aluminum oxide that delivers a faster, more consistent cut compared to conventional ceramic aluminum oxide belts. At 80 grit and sized 18 inches long by 1/2 inch wide, this belt suits tight-radius and contoured grinding tasks. A YF-weight polyester backing provides moderate flexibility, and a waterproof construction allows use in both wet and dry environments. A built-in grinding aid reduces heat buildup, extending belt life on heat-sensitive alloys.

This belt is used in industrial metalworking applications including weld blending, surface prep, and finish grinding on ferrous and non-ferrous metals. Its design is well suited for robotic grinding systems and pressure-assisted equipment where consistent performance and reduced changeout frequency are priorities. The waterproof YF-weight polyester backing handles both wet coolant-assisted passes and dry runs without degradation. Fabricators, maintenance machinists, and metal finishing technicians working on both straight and contoured workpieces will find this belt appropriate for production environments where throughput and abrasive life directly affect operating costs.

Key Features

• Precision-Shaped Grain blend of shaped ceramic and premium aluminum oxide for faster, consistent cut at medium pressure
• Durable resin bond resists heat-related deterioration, extending belt service life
• Waterproof YF-weight polyester backing supports wet and dry use on all metals
• Moderately flexible backing conforms to straight and contoured surfaces during grinding and blending
• Integrated grinding aid cools the cut on heat-sensitive alloys, reducing discoloration and thermal damage
• Suitable for robotic and pressure-assisted applications, reducing downtime from frequent belt changes

Compatibility

Designed for use on all metals in medium-pressure grinding and blending applications; compatible with belt grinders and robotic grinding systems that accept 18-inch by 1/2-inch abrasive belts.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt equipment. Confirm the machine is powered off and all guards are in place before mounting the belt. Verify belt tracking and tension according to the equipment manufacturer's specifications before operating. Always follow applicable ANSI and shop safety standards when working with abrasive products.
