3M 7010309420 Trizact 307EA Abrasive Belt 72x2 Inch

Product Description

The 3M 7010309420 is a Trizact 307EA coated abrasive belt designed for intermediate finishing and fine polishing operations. It uses microreplication technology in which micron-graded aluminum oxide particles are formed into uniform three-dimensional pyramids bonded to a flexible rayon cloth backing. As the pyramids wear during use, fresh, sharp mineral is continuously exposed, delivering a consistent cut rate and a predictable, fine surface finish throughout the belt's service life. This belt measures 72 inches in length and 2 inches in width, making it suited for standard belt finishing equipment used in fabrication and metalworking environments.

This belt is intended for metalworking applications requiring repeatable fine finishes prior to plating, buffing, or surface coating. Its flexible rayon backing conforms to contoured and irregular workpiece profiles, making it effective for both flat and shaped stock. The three-dimensional abrasive structure also supports consistent performance in automated and robotic finishing lines where uniform stock removal and surface finish are critical across high-volume production runs. It is appropriate for use in light manufacturing, job shops, and industrial finishing operations.

Key Features

• Microreplication technology forms aluminum oxide into uniform abrasive pyramids for self-sharpening action
• Continuously exposes fresh mineral as pyramids wear, maintaining consistent cut and finish quality
• Flexible rayon cloth backing conforms to contoured surfaces for even contact
• Three-dimensional abrasive design supports predictable, repeatable finishes in robotic or automated applications
• Produces finer surface finishes than conventional electrostatically coated abrasive belts
• Suited for intermediate finishing and fine polishing stages prior to plating or buffing

Compatibility

Designed for use on standard belt finishing and grinding equipment accepting 72-inch by 2-inch abrasive belts in metalworking and fabrication applications.

Installation Notes

Installation should be performed by a qualified machine operator familiar with belt finishing equipment. Power down and de-energize the machine completely before changing belts. Confirm belt tracking and tension per the equipment manufacturer's guidelines before resuming operation. Inspect the belt for tears or delamination prior to each use.
