3M 7010360289 Abrasive Belt 90 X 4 Inch Aluminum Oxide

Product Description

The 3M 7010360289 is a Trizact 237AA coated abrasive belt designed for intermediate finishing and fine polishing in metalworking and fabrication environments. It uses 3M microreplication technology, where micron-graded aluminum oxide mineral is formed into three-dimensional pyramids and bonded to an X-weight cloth backing. As the pyramids wear, fresh, sharp cutting edges are continuously exposed, delivering a consistent cut rate and a predictable, fine finish throughout the belt's life. This belt measures 90 inches in length and 4 inches in width. It is installed and used by metalworkers, fabricators, and finishing technicians in both manual and automated grinding setups.

This belt is suited for robotic and automated finishing applications where consistent surface finish is critical across high production volumes. It is also used in manual belt grinding operations for intermediate stock removal and fine polishing steps that precede plating, buffing, or coating processes. The flexible cloth backing allows the belt to conform to contoured workpiece surfaces, making it effective on complex geometries as well as flat stock. It is appropriate for use on metals that require tight finish tolerances before downstream surface treatment.

Key Features

• Microreplication technology forms aluminum oxide mineral into self-sharpening pyramids for consistent cut throughout belt life
• Self-sharpening pyramid structure runs cooler than conventional abrasives, reducing heat-related workpiece damage
• X-weight cloth backing provides flexibility for finishing over contours and irregular surfaces
• Three-dimensional abrasive design maintains predictable, repeatable finishes in robotic and automated applications
• Produces finer surface finishes than conventionally electrostatically coated abrasive belts
• Suited for intermediate finishing and fine polishing prior to plating or buffing operations

Compatibility

Designed for use on belt grinding and finishing machines that accept 90-inch by 4-inch abrasive belts. Suitable for metalworking applications requiring consistent intermediate to fine finishes on ferrous and non-ferrous workpieces prior to plating or buffing.

Installation Notes

Installation should be performed by qualified metalworking or maintenance personnel familiar with belt grinder operation and safety procedures. Power down and lock out the grinding machine before changing the belt. Verify belt tracking and tension according to the equipment manufacturer's specifications before resuming operation. Always wear appropriate personal protective equipment, including eye and face protection, when operating belt grinding equipment.
