3M 7100191862 Cubitron Ii 784F Belt 60 Grit 106x4 Inch

Product Description

The 3M 7100191862 is a Cubitron II 784F cloth abrasive belt engineered for medium-pressure grinding and blending on metal surfaces. It measures 106 inches long by 4 inches wide and runs at 60 grit. The belt uses 3M Precision-Shaped Grain, a proprietary blend of shaped ceramic and premium aluminum oxide minerals that delivers a faster, more consistent cut than conventional ceramic aluminum oxide abrasives. A durable resin bond resists heat-related breakdown, and a waterproof YF-weight polyester backing supports both wet and dry operation. A built-in grinding aid cools the cutting zone, making it well suited for heat-sensitive alloys and extended run applications.

This belt is intended for industrial and fabrication environments where consistent material removal and reduced downtime are priorities. Typical applications include grinding, blending, and finishing on flat and contoured metal surfaces. The moderately flexible backing conforms to both straight and curved workpieces. It performs in robotic, pressure-assisted, and manual belt grinder setups, handling ferrous and non-ferrous metals. The 60-grit specification positions it in medium stock removal work where surface prep quality matters alongside throughput.

Key Features

• Precision-Shaped Grain blend of shaped ceramic and aluminum oxide for longer service life than conventional aluminum oxide belts
• Faster, more consistent cut rate on medium-pressure grinding and blending operations
• Resin bond resists heat deterioration, extending belt life in sustained grinding cycles
• Waterproof YF-weight polyester backing supports wet and dry use on all metals
• Built-in grinding aid cools abrasive contact zone, protecting heat-sensitive alloys
• Moderately flexible backing conforms to straight and contoured surfaces
• Suitable for robotic and pressure-assisted applications, reducing changeout frequency

Compatibility

Designed for use on all metals, including ferrous and non-ferrous alloys, in belt grinder and finishing machine applications requiring a 106-inch by 4-inch belt at 60 grit.

Installation Notes

Belt installation and replacement should be performed by qualified grinding or fabrication personnel following the machine manufacturer's guidelines. Power down and lock out the belt grinder before changing the belt. Verify belt tracking, tension, and guard clearance before resuming operation. Confirm the belt arrow or run-direction marking aligns with machine rotation to prevent premature joint failure.
