3M 7100119733 Abrasive Belt 118x3 Inch Aluminum Oxide

Product Description

The 3M 7100119733 is a Trizact 307EA cloth abrasive belt designed for intermediate finishing and fine polishing on metal and other hard surfaces. It uses microreplication technology in which micron-graded aluminum oxide mineral is formed into uniform three-dimensional pyramids and bonded to a flexible rayon cloth backing. As the pyramids wear during use, fresh sharp mineral is continuously exposed, producing a consistent cut rate and a predictable fine finish throughout the life of the belt. This belt measures 118 inches in length and 3 inches in width. It is suited for use in automated, robotic, and manual finishing operations.

This belt is designed for intermediate and fine finishing stages prior to plating, buffing, or coating. The flexible rayon backing allows the belt to conform to contoured and irregular surfaces, making it effective for both flat stock and shaped workpieces. It is well suited for metalworking facilities, fabrication shops, and production environments where consistent surface finish is required across high-volume runs. Robotic and automated sanding systems benefit from the predictable wear characteristics of the microreplication construction.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening abrasive pyramids for consistent cut and finish
• Self-sharpening design runs cooler than conventional abrasives, reducing heat buildup on workpieces
• Flexible rayon cloth backing conforms to contoured surfaces for uniform contact
• Three-dimensional abrasive structure delivers repeatable finishes throughout belt life, critical in robotic applications
• Produces finer surface finishes than conventionally electrostatically coated abrasive belts
• Suitable for finishing prior to plating or buffing operations

Compatibility

Designed for use on belt grinders, stroke sanders, and automated finishing equipment that accept belts measuring 118 inches in length and 3 inches in width.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt equipment. Ensure the machine is powered off and all guards are in place before mounting the belt. Verify belt tracking and tension according to the equipment manufacturer guidelines before resuming operation. Inspect the belt for damage before each use and replace if tearing, delamination, or glazing is present.
