3M 7010328245 Trizact 217EA Abrasive Belt 148x2.25 in

Product Description

The 3M 7010328245 is a Trizact 217EA coated abrasive belt engineered for intermediate finishing and fine polishing applications. It uses microreplicated technology in which micron-graded aluminum oxide mineral is formed into uniform pyramidal structures 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 a predictable fine finish throughout the belt's service life. A built-in grinding aid helps dissipate heat, reducing the risk of warping or discoloration on workpiece surfaces. Licensed tradespeople and finishing professionals working in metal fabrication and surface prep are the primary installers and users of this product.

This belt measures 148 inches in length and 2.25 inches in width, making it suitable for wide-belt and long-belt finishing machines used in industrial and production environments. It is well suited for light-pressure applications requiring controlled mineral breakdown, consistent surface texture, and preparation for downstream processes such as plating or buffing. The flexible rayon cloth backing conforms to contoured surfaces, making the belt effective on both flat stock and irregular profiles. Its consistency and long service life also make it a strong candidate for robotic and automated finishing setups where repeatable results are critical.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral as they wear, maintaining a consistent cut throughout belt life
• JE-weight rayon cloth backing provides flexibility for contoured and irregular surface finishing
• Grinding aid reduces heat buildup, helping prevent workpiece warping and discoloration
• Engineered for light-pressure applications with controlled mineral breakdown for uniform finishes
• Produces finer surface finishes than conventional coated abrasives
• Consistent performance makes this belt well suited for robotic and automated finishing lines

Compatibility

Designed for use on wide-belt and long-belt abrasive finishing machines that accept a 148-inch by 2.25-inch belt. Suitable for metal finishing workflows requiring intermediate grit preparation prior to plating or buffing operations.

Installation Notes

Belt installation and tensioning should be performed by a qualified machine operator or finishing technician following the equipment manufacturer's guidelines. Disengage and lock out all power to the finishing machine before mounting or replacing the belt. Verify that belt tracking is properly set before resuming operation. Inspect the belt for tears or edge damage before each use and replace if any defects are found.
