3M 7100018545 Abrasive Belt 132x4 Inch 120 Grit Alumina Zirconia

Product Description

The 3M 7100018545 is a coated abrasive belt designed for demanding grinding and finishing applications on metal and other substrates. Built with alumina zirconia abrasive grain and a grinding aid, it delivers faster cutting rates than conventional aluminum oxide belts. The belt measures 132 inches in length and 4 inches in width, making it suited for wide-contact grinding operations. A heavyweight, water-resistant polyester cloth backing gives it the durability needed for high-pressure applications and edge work. It runs cooler than standard abrasives, which is critical when working on heat-sensitive metals. Licensed tradespeople in fabrication and metalworking shops are the primary installers and users.

This belt is used in production grinding, weld blending, and surface conditioning on ferrous and non-ferrous metals including aluminum and stainless steel. The 120-grit designation places it in the fine-to-medium range, suitable for finishing passes after heavier stock removal. It fits belt grinders and wide-belt sanding machines configured for 132-inch by 4-inch belts. The alumina zirconia mineral provides consistent performance across a range of substrates, making this belt a practical choice for shops running mixed-material workflows.

Key Features

• Alumina zirconia grain with grinding aid cuts faster than aluminum oxide abrasives
• Runs cool during operation, reducing the risk of heat damage on aluminum and stainless steel
• Heavyweight water-resistant polyester cloth backing withstands high-pressure grinding and edge work
• 120-grit finish suitable for blending, finishing, and light stock removal
• Coated construction for consistent grain exposure throughout the belt life

Compatibility

Designed for use on belt grinders and wide-belt machines accepting 132-inch by 4-inch abrasive belts. Performs on ferrous metals, non-ferrous metals, and other substrates where alumina zirconia grain is appropriate.

Installation Notes

Installation should be performed by a qualified machine operator familiar with belt grinder setup and safe abrasive handling. Ensure the machine is fully powered down and locked out before changing belts. Verify belt tracking alignment before resuming operation. Always wear appropriate PPE including eye protection and gloves when handling and mounting abrasive belts.
