3M 7100117456 Trizact 237AA Abrasive Belt 132x3 Inch

Product Description

The 3M 7100117456 is a Trizact 237AA coated abrasive belt engineered for intermediate finishing and fine polishing applications in metalworking and fabrication environments. It uses 3M microreplication technology, where micron-graded aluminum oxide particles are formed into precise three-dimensional pyramids and bonded to an X-weight cloth backing. As the abrasive pyramids wear, fresh sharp mineral is continuously exposed, delivering a consistent cut rate and a predictable fine finish throughout the life of the belt. Licensed tradespeople and automated-line operators rely on this belt ahead of plating and buffing operations.

This belt measures 132 inches in length and 3 inches in width, making it suited for wide-format grinding and finishing equipment used in industrial fabrication shops, metal service centers, and automated robotic finishing lines. Its flexible cloth backing conforms to contours, making it effective for both flat stock and irregular profiles. The three-dimensional abrasive structure maintains finish consistency across the full belt life, which is particularly valuable in robotic and high-volume production applications where repeatable results are required.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening abrasive pyramids for consistent cut and finish
• Self-sharpening pyramid design runs cooler than conventional coated abrasives, reducing heat-related workpiece damage
• X-weight cloth backing provides flexibility for consistent finishing over contoured surfaces
• Three-dimensional abrasive structure maintains uniform finish throughout belt life, ideal for robotic applications
• Produces finer finishes than conventional electrostatically coated abrasives
• Designed for intermediate finishing and fine polishing prior to plating or buffing operations

Compatibility

Designed for use on belt finishing and grinding machines accepting a 132-inch by 3-inch abrasive belt; suited for metalworking applications involving steel, stainless steel, and non-ferrous alloys ahead of plating, buffing, or polishing operations.

Installation Notes

Belt installation and tensioning should be performed by qualified machine operators following the equipment manufacturer's guidelines. Power down and lockout the machine before mounting or changing the belt. Inspect the belt for nicks, tears, or tracking damage before each use. Ensure the belt tracks correctly on the machine's contact wheel and platen before resuming production.
