3M 7100191861 Cubitron Ii 784F Belt 36 Grit 106x4 Inch

Product Description

The 3M 7100191861 is the Cubitron II 784F cloth abrasive belt, engineered for medium-pressure grinding and blending on all metals. It uses 3M Precision-Shaped Grain technology, a proprietary blend of shaped ceramic and premium aluminum oxide minerals, to deliver a faster and more consistent cut than conventional ceramic aluminum oxide belts. The 36-grit rating and YF-weight polyester backing make this belt well suited to aggressive stock removal on both flat and contoured workpieces. A durable resin bond resists heat-induced deterioration, and an integrated grinding aid helps keep temperatures in check on heat-sensitive alloys.

This belt is designed for use in robotic, pressure-assisted, and manual grinding and blending operations across fabrication, weld blending, and surface conditioning workflows. It measures 106 inches in length and 4 inches in width, fitting wide-belt and stroke-sander configurations common in production metalworking environments. The waterproof backing supports both wet and dry application conditions, making it adaptable to a range of shop setups. Licensed fabricators, metal finishing technicians, and production grinders are the primary users.

Key Features

Installation Notes

Belt installation should be performed by qualified personnel following the equipment manufacturer's belt-tensioning and tracking procedures. Power down and lock out the grinding machine before mounting or removing the belt. Confirm belt direction-of-travel arrow aligns with the machine's drive direction prior to startup. Inspect the contact wheel or platen for wear or damage before mounting a new belt.
