3M 7000118669 Trizact 237AA Abrasive Belt 18x3/4 Inch Ao

Product Description

The 3M 7000118669 is a Trizact 237AA abrasive belt engineered for intermediate finishing and fine polishing applications in metalworking and fabrication environments. It measures 18 inches in length and 3/4 inch in width. The belt uses 3M microreplication technology, where micron-graded aluminum oxide abrasive particles are formed into three-dimensional pyramidal structures and bonded to an X-weight cloth backing. As the pyramids wear down during use, fresh, sharp mineral is continuously exposed, delivering a consistent cut rate and repeatable surface finish throughout the life of the belt.

This belt is suited for ferrous and non-ferrous metal finishing operations requiring controlled, uniform surface profiles prior to plating, buffing, or final polishing steps. The flexible cloth backing allows the belt to conform to contoured workpiece geometries, making it well-suited for both manual grinding operations and automated robotic finishing systems where consistent finish quality across the full belt life is required.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening pyramidal structures for consistent cut and finish
• Self-sharpening mineral continuously exposes fresh abrasive as pyramids wear, extending usable belt life
• Runs cooler than conventional abrasives, reducing heat buildup on workpiece surfaces
• Flexible X-weight cloth backing conforms to contoured surfaces for uniform finish
• Three-dimensional abrasive design delivers predictable, repeatable finishes in robotic finishing applications
• Produces finer surface finishes than conventionally electrostatically coated abrasive belts

Compatibility

Designed for use on belt grinding and finishing machines that accept 18-inch by 3/4-inch abrasive belts; intended for intermediate finishing and fine polishing of metal parts prior to plating or buffing operations.

Installation Notes

Abrasive belts should be installed by qualified personnel following the machine manufacturer's belt-tensioning and tracking guidelines. Power down and lock out the grinder or finishing machine before changing belts. Inspect the belt for tears or damage before mounting. Ensure belt direction of travel matches the arrow marked on the belt backing if directional markings are present.
