3M 7100020318 Abrasive Belt 80 Grit 75x37 Inch Ceramic Ao

Product Description

The 3M 7100020318 is a coated abrasive cloth belt designed for demanding stock removal and metal finishing applications. It combines 3M Ceramic Abrasive Grain with aluminum oxide in a blend that cuts faster and lasts longer than traditional aluminum oxide abrasives. The belt measures 75 inches in length and 37 inches in width with an 80-grit rating. A heavyweight polyester backing supports high-pressure grinding and can be run dry or with a lubricant, making it well suited for production metalworking environments. A built-in grinding aid reduces heat generation, which is especially useful when working with heat-sensitive metals such as stainless steel.

This belt is intended for industrial and trade applications including metal fabrication, weld blending, surface conditioning, and precision stock removal. It performs in both wet and dry setups, making it adaptable to shop grinding equipment where belt changes need to be minimized and throughput matters. The ceramic-AO grain blend is particularly effective on carbon steel, stainless steel, and other ferrous metals where consistent cut rate and finish quality are required across the life of the belt.

Key Features

• Ceramic and aluminum oxide grain blend for faster cutting and longer belt life versus standard AO belts
• 80-grit rating suited for aggressive stock removal and metal finishing
• Heavyweight polyester backing handles high-pressure applications without breaking down
• Runs wet or dry, compatible with lubricant-fed grinding setups
• Integrated grinding aid reduces heat buildup when grinding stainless steel and heat-sensitive alloys
• Durable resin bond resists heat deterioration to extend usable belt life

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive belt for industrial belt grinding machines and finishing equipment that accept 75-inch by 37-inch belts.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt grinding equipment. Power down and lock out the grinder before mounting or removing the belt. Confirm belt tracking and tension per the equipment manufacturer's guidelines before resuming operation. Inspect the belt for tears or separation before each use and do not exceed the machine's rated operating speed.
