3M 7000119520 Abrasive Belt 20.5x0.75 Inch Cubitron Ii 984F

Product Description

The 3M 7000119520 is a Cubitron II 984F coated abrasive belt built for demanding metalworking applications. It runs on a YF-weight polyester cloth backing and uses 3M Precision-Shaped Grain technology, which continuously fractures into sharp cutting points to maintain fast, aggressive stock removal throughout the belt's life. A grinding aid is incorporated into the construction to reduce heat buildup during use, which lowers the risk of metal discoloration, oxidation, and heat-related stress cracking. This belt measures 20.5 inches in length and 0.75 inches in width and is sold individually. It is installed and used by machinists, fabricators, and industrial grinders working with high-value alloys and critical metal components.

This belt is engineered for medium to high pressure grinding applications on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys. It is well suited for robotic grinding systems and pressure-assisted belt grinding setups where extended belt life and reduced changeover time directly impact production output. The combination of a durable polyester cloth backing and Precision-Shaped Grain makes it a reliable choice for high-cycle industrial environments where heat management and consistent cut rate are priorities.

Key Features

• Precision-Shaped Grain fractures continuously into sharp points for fast, sustained cut rates
• YF-weight polyester cloth backing handles medium to high pressure grinding without breakdown
• Built-in grinding aid reduces heat generation, minimizing discoloration and oxidation on finished surfaces
• Engineered to reduce stress cracks caused by heat on stainless steel and exotic alloys
• Extended belt life reduces changeover frequency in robotic and pressure-assisted applications
• Suitable for stainless steel, carbon steel, cobalt chrome, nickel alloys, and exotic alloys

Compatibility

Designed for use on medium to high pressure belt grinding machines, including robotic and pressure-assisted systems, when working with stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys.

Installation Notes

Installation should be performed by qualified operators familiar with belt grinding equipment and abrasive product handling. Power down and de-energize the grinder before mounting or removing the belt. Verify belt tracking and tension according to the machine manufacturer's specifications before resuming operation. Inspect the belt for damage or wear before each use and replace immediately if tears, delamination, or excessive glazing are observed.
