3M 7100191891 Cubitron Ii 984F Abrasive Belt 120 Grit

Product Description

The 3M 7100191891 is a Cubitron II 984F precision abrasive belt engineered for demanding metal grinding and finishing applications. It features 3M Precision-Shaped Grain on a YF-weight polyester cloth backing, delivering fast, consistent stock removal. A built-in grinding aid keeps the belt running cooler than conventional abrasives, reducing heat-related discoloration, oxidation, and stress cracking in the workpiece. This belt measures 60 inches in length and 6 inches in width and is rated at 120 grit. It is installed and used by metal fabricators, weld prep technicians, and industrial grinding operators working with high-value alloys where surface integrity matters.

This belt is designed for medium to high pressure applications on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys. It performs well in robotic grinding cells and pressure-assisted machine applications where consistent belt life and reduced changeout frequency directly affect throughput. The YF-weight polyester cloth backing provides the rigidity and durability needed for sustained high-pressure contact without backing failure or premature breakdown of the abrasive layer.

Key Features

• Precision-Shaped Grain continuously fractures to expose sharp cutting points, maintaining fast cut rates throughout belt life
• Integrated grinding aid reduces heat buildup, minimizing metal discoloration and heat-induced stress cracks
• YF-weight polyester cloth backing rated for medium to high pressure grinding on stainless and exotic alloys
• Extended belt life compared to conventional abrasive belts, reducing changeouts and machine downtime
• Well-suited for robotic and pressure-assisted grinding applications requiring consistent, repeatable performance

Compatibility

Designed for use on belt grinders and wide-belt machines accepting 60 inch by 6 inch abrasive belts. Optimized for grinding stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys at medium to high contact pressures.

Installation Notes

Belt installation should be performed by qualified machine operators or maintenance technicians familiar with the specific grinding equipment in use. Power down and lockout the machine before changing belts. Verify belt tracking and tension per the equipment manufacturer's guidelines before resuming operation. Inspect the contact wheel and platen for wear or damage that could cause uneven belt loading or premature failure.
