3M 7100018547 Abrasive Belt 132x3 Inch Aluminum Oxide

Product Description

The 3M 7100018547 is a Trizact 307EA abrasive belt designed for intermediate finishing and fine polishing on metal and other hard surfaces. It uses a microreplication process in which micron-graded aluminum oxide particles are formed into three-dimensional pyramids and bonded to a flexible rayon cloth backing. As the pyramids wear during use, fresh, sharp mineral is continuously exposed. This self-sharpening action produces a consistent cut rate and a predictable, fine finish across the full life of the belt. The belt measures 132 inches in length and 3 inches in width and weighs 0.41 pounds.

This belt is suited for robotic and automated finishing lines as well as manual applications where repeatable, fine surface finishes are required. It is commonly used in metalworking operations ahead of plating, buffing, or final polishing stages. The flexible rayon backing conforms to contoured and curved workpiece surfaces, making it effective for parts with irregular geometry. It is typically used by metal fabricators, industrial maintenance technicians, and manufacturing operations requiring controlled, consistent scratch patterns.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening abrasive pyramids for consistent cut and finish
• Pyramids run cooler than conventional abrasives, reducing heat-related workpiece distortion
• Flexible rayon cloth backing conforms to contoured and curved surfaces
• Three-dimensional abrasive structure delivers consistent finishes throughout belt life in robotic applications
• Produces finer finishes than conventional electrostatically coated abrasive belts
• Designed for intermediate finishing and fine polishing prior to plating or buffing

Compatibility

Designed as an OEM-style abrasive belt for use on belt grinders and finishing machines accommodating a 132-inch by 3-inch belt configuration.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt equipment. Power down and lockout the belt grinder or finishing machine before mounting or removing the belt. Confirm belt tracking and tension according to the machine manufacturer guidelines before resuming operation. Inspect the belt for tears or edge damage prior to each use.
