3M 7010364866 Abrasive Belt 118x2.5 Inch Ao Rayon

Product Description

The 3M 7010364866 is a Trizact 307EA coated abrasive belt built on a flexible rayon cloth backing with aluminum oxide abrasive mineral formed into microscopic pyramidal structures using 3M microreplication technology. As the pyramids wear during use, fresh cutting mineral is continuously exposed, delivering a consistent cut rate and predictable surface finish throughout the life of the belt. At 118 inches long and 2.5 inches wide, this belt is sized for wide-contact applications where finish uniformity and run temperature matter. It is installed and operated by metalworking technicians and finishing specialists in production and job-shop environments.

This belt is designed for intermediate finishing and fine polishing operations on metal substrates prior to plating, buffing, or coating. The flexible rayon backing conforms to contoured and irregular surfaces, making it well suited for both flat-pass and contact-wheel applications. The three-dimensional abrasive structure produces highly repeatable surface finishes, which makes it a reliable choice for automated and robotic finishing lines where consistency across a production run is required.

Key Features

• Microreplication technology forms aluminum oxide particles into self-sharpening pyramidal structures for consistent cut throughout abrasive life
• Continuously exposed fresh mineral reduces heat buildup compared to conventional coated abrasives
• Flexible rayon cloth backing conforms to contoured and complex surfaces
• Produces finer, more uniform finishes than conventionally electrostatically coated abrasive belts
• Suited for intermediate finishing and fine polishing steps before plating or buffing
• Three-dimensional abrasive design supports repeatable results in robotic and automated finishing applications

Compatibility

Designed for use on belt grinders and finishing machines that accept 118-inch by 2.5-inch abrasive belts; confirm drive and idler wheel spacing and contact pressure settings before installation.

Installation Notes

Metalworking or finishing technicians should power down and lock out the belt grinder or finishing machine before changing belts. Verify belt tracking alignment and tension after installation before resuming operation. Always confirm the belt runs in the correct direction of travel if an arrow is marked on the backing. Appropriate eye protection and respiratory PPE should be worn when operating abrasive belts on metal substrates.
