3M 7000118678 Abrasive Belt 42 Inch Aluminum Oxide Cloth

Product Description

The 3M 7000118678 is a Trizact 237AA coated abrasive belt designed for intermediate finishing and fine polishing in demanding production environments. It uses 3M microreplication technology, where micron-graded aluminum oxide mineral is formed into uniform three-dimensional pyramids and bonded to an X-weight 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 from start to end of belt life. This belt is installed and used by metalworking professionals, fabricators, and finishing technicians in production and robotic grinding applications.

This belt is suited for intermediate finishing and fine polishing operations prior to plating or buffing. The flexible X-weight cloth backing conforms to contoured workpiece surfaces, making it appropriate for both flat stock and complex profiles. Its three-dimensional abrasive structure supports consistent finish results across high-volume and robotic applications where repeatability is critical. The gray color indicates the Trizact 237AA abrasive formulation.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening abrasive pyramids for consistent cut and finish
• Fresh mineral continuously exposed as pyramids wear, extending usable belt life
• Runs cooler than conventional coated abrasives, reducing heat-related workpiece damage
• Flexible X-weight cloth backing conforms to contours for uniform surface finishing
• Three-dimensional abrasive design supports repeatable finishes in robotic and automated applications
• Produces finer finishes than conventional electrostatically coated abrasives

Compatibility

Designed as a replacement or production abrasive belt for belt grinders, finishing machines, and robotic grinding systems that accept 42-inch length by 1-inch width abrasive belts.

Installation Notes

Belt installation should be performed by a qualified operator following the equipment manufacturer's guidelines for belt grinders or finishing machines. Disengage and lock out power to the machine before changing the belt. Verify belt tracking and tension per machine specifications before resuming operation. Inspect the belt for tears or edge damage before each use.
