3M 7100122889 Cubitron Ii 784F Abrasive Belt 80 Grit

Product Description

The 3M 7100122889 is a Cubitron II 784F cloth abrasive belt engineered for medium-pressure grinding and blending on metal surfaces. It measures 48 inches long by 6 inches wide and carries an 80-grit rating. The belt uses 3M Precision-Shaped Grain — a proprietary blend of shaped ceramic and premium aluminum oxide — to deliver faster, more consistent stock removal compared to conventional ceramic aluminum oxide belts. A YF-weight polyester backing provides moderate flexibility, and a waterproof construction with integrated grinding aid makes it suitable for both wet and dry applications. Industrial fabricators, weld-finishing crews, and robotic grinding cells are the primary users.

This belt is intended for medium-pressure grinding and blending on all metals, including heat-sensitive alloys where the built-in grinding aid helps control heat buildup. The moderately flexible YF-weight polyester backing conforms to both straight and contoured workpiece profiles, making it effective in manual, pressure-assisted, and robotic belt-grinding setups. It is sold individually and is well suited to production environments where belt life and consistent cut rate directly affect throughput and downtime.

Key Features

• Precision-Shaped Grain blend of shaped ceramic and premium aluminum oxide for longer life and faster cut than conventional belts
• Moderately flexible YF-weight polyester backing conforms to straight and contoured surfaces
• Waterproof construction supports both wet and dry grinding applications
• Integrated grinding aid cools the abrasive interface on heat-sensitive alloys
• Durable resin bond resists heat deterioration, extending usable belt life
• Reduces changeouts and downtime in robotic and pressure-assisted grinding setups

Compatibility

Designed for use on all metals in medium-pressure grinding and blending applications, including robotic and pressure-assisted belt-grinding equipment that accepts a 48-inch by 6-inch abrasive belt.

Installation Notes

Belt installation and replacement should be performed by a qualified operator following the grinder or belt-sander manufacturer's guidelines. Power down and lock out the machine before mounting or removing the belt. Verify belt tracking and tension per equipment specifications before resuming operation. Always wear appropriate PPE, including eye protection and gloves, when handling abrasive belts.
