3M 7100078552 Cubitron Ii 984F Abrasive Belt 132x3 Inch 50 Grit

Product Description

The 3M 7100078552 is the Cubitron II 984F coated abrasive belt, built on a YF-weight polyester cloth backing and engineered for demanding material removal in industrial grinding applications. It measures 132 inches in length and 3 inches in width with a 50 grit rating. The belt uses 3M Precision-Shaped Grain technology, which continuously fractures during use to expose sharp new cutting points. This design delivers fast, consistent stock removal while generating less heat than conventional abrasive belts, helping prevent discoloration, oxidation, and heat-related stress cracking in finished workpieces. A built-in grinding aid further supports cooler cutting action.

This belt is designed for medium to high pressure grinding applications on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys. It performs well in both robotic and pressure-assisted grinding setups where consistent cut rate and extended belt life directly reduce downtime and changeout frequency. Fabrication shops, aerospace component manufacturers, and industrial metalworking operations are the primary users. The 132-inch length suits large-format belt grinders and automated grinding cells running continuous-contact or contact-wheel configurations.

Key Features

• 3M Precision-Shaped Grain fractures continuously to maintain sharp cutting points and fast stock removal
• Engineered for cooler operation, reducing metal discoloration, oxidation, and heat-related stress cracking
• Built-in grinding aid extends belt life and supports consistent performance in high-pressure applications
• YF-weight polyester cloth backing handles medium to high pressure without deformation or delamination
• Extended belt life reduces changeouts and downtime in robotic and pressure-assisted grinding systems
• Produces more finished parts per belt compared to conventional coated abrasive belts

Compatibility

Designed for use on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys in medium to high pressure belt grinding applications. Suitable for robotic and pressure-assisted grinding equipment accepting 132-inch by 3-inch belts.

Installation Notes

Installation is typically performed by a maintenance technician or machine operator following equipment lockout and tagout procedures before accessing the belt drive. Confirm belt tracking and tension according to the grinder manufacturer specifications before resuming operation. Inspect contact wheels and platens for wear before mounting a new belt, as damaged contact surfaces accelerate belt wear and reduce cut quality. Always run the belt in the direction indicated by the arrow on the backing splice.
