3M 7010361421 Trizact 217EA Abrasive Belt 168x4 Inch Ao

Product Description

The 3M 7010361421 is a Trizact 217EA coated abrasive belt designed for intermediate finishing and fine polishing on metal surfaces. It uses proprietary microreplication technology in which micron-graded aluminum oxide particles are formed into precisely shaped pyramids and bonded to a JE-weight rayon cloth backing. As the pyramids wear during use, fresh, sharp mineral is continuously exposed, delivering a consistent cut rate and predictable surface finish throughout the life of the belt. At 168 inches long and 4 inches wide, this belt fits wide-format industrial belt grinding and polishing machines. Licensed tradespeople and metalworking technicians install and operate these belts on production and finishing equipment.

This belt is suited for intermediate cut-down and fine polishing steps prior to electroplating or buffing operations. The flexible JE-weight rayon cloth backing conforms to contoured and complex surface geometries, making it appropriate for both flat stock and shaped workpieces. Its consistent cut behavior and extended abrasive life make it well suited for automated and robotic finishing lines, where predictability and repeatability across large production runs are critical. It is designed for light-pressure applications where controlled mineral breakdown is needed to maintain finish quality.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral as they wear, maintaining consistent cut throughout belt life
• JE-weight rayon cloth backing provides flexibility for finishing over contoured surfaces
• Consistent cut rate and long service life support robotic and automated finishing applications
• Engineered for intermediate finishing and fine polishing prior to plating or buffing
• Performs under light pressure conditions while maintaining controlled mineral breakdown and finish quality
• Grinding aid incorporated into the construction helps reduce heat buildup, minimizing risk of warping or discoloration of workpieces

Compatibility

Designed as a replacement-style abrasive belt for industrial belt grinders and polishing machines accepting a 168-inch by 4-inch belt configuration.

Installation Notes

Belt installation and machine setup should be performed by qualified personnel familiar with industrial abrasive equipment. Power down and de-energize the machine completely before changing belts. Verify belt tracking and tension per the equipment manufacturer's guidelines before resuming operation. Inspect the belt splice and backing for damage before use.
