3M 7100101153 Cubitron Ii 984F Belt 120 Grit 18x0.5 in

Product Description

The 3M 7100101153 is the Cubitron II 984F coated abrasive belt designed for high-speed stock removal on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys. Built on a YF-weight polyester cloth backing, it uses 3M Precision-Shaped Grain technology, which continuously fractures to expose sharp new cutting points throughout the belt's life. At 120 grit and measuring 18 inches long by 0.5 inches wide, this belt is engineered for medium to high pressure applications in production grinding environments. A built-in grinding aid reduces heat buildup during cut, helping prevent surface discoloration and heat-related stress cracks on sensitive alloys. Metal fabricators, weld grinding operators, and robotic finishing cells are the primary users.

This belt is suited for robotic, automated, and pressure-assisted belt grinding operations where consistent cut rate and long belt life are critical. It performs well on contact wheel and platen grinder setups processing stainless steel tubing, aerospace alloy components, medical device parts, and similar workpieces requiring controlled surface finish. The 120 grit rating positions it for medium stock removal and pre-finish passes. Its cooler-running construction makes it especially appropriate on heat-sensitive alloys such as cobalt chrome and nickel-based superalloys where discoloration or metallurgical stress is a concern.

Key Features

• Precision-Shaped Grain continuously fractures to maintain sharp cutting edges and fast cut rate throughout belt life
• Engineered cooler-running construction reduces metal discoloration, oxidation, and heat-related stress cracking
• Built-in grinding aid supports performance on stainless steel, cobalt chrome, nickel alloys, and carbon steel
• YF-weight polyester cloth backing handles medium to high pressure grinding demands without premature breakdown
• Extended belt life reduces changeouts and downtime in robotic and pressure-assisted applications
• 120 grit rating suitable for medium stock removal and pre-finish grinding passes

Compatibility

Designed for use on belt grinders and robotic grinding systems operating on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys in medium to high pressure applications.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's belt-change procedure. Power down and lock out the grinder before removing the spent belt and fitting the new one. Confirm belt tracking and tension per the machine's specifications before resuming operation. Inspect the contact wheel and platen for wear or damage each time a belt is changed.
