3M 7010309385 Abrasive Belt 80 Grit 168x18 Inch Ceramic Ao

Product Description

The 3M 7010309385 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 conventional aluminum oxide belts. The heavyweight polyester cloth backing handles high-pressure grinding and can be run dry or with lubricant, making it suitable for a range of metalworking environments. At 168 inches long and 18 inches wide with an 80 grit rating, this belt is built for wide-platen and large-format belt grinder applications handled by fabricators, machinists, and metal finishing professionals.

This belt is well suited for industrial metal finishing, weld blending, and high-volume stock removal on ferrous and non-ferrous metals. The ceramic aluminum oxide grain blend is particularly effective on stainless steel, where a built-in grinding aid helps manage heat generation during aggressive grinding passes. The durable resin bond resists heat deterioration, extending belt life in production settings where frequent belt changes reduce throughput. It performs consistently in both dry grinding and wet lubricated setups.

Key Features

• Ceramic and aluminum oxide grain blend delivers faster cut rate and longer life than standard aluminum oxide belts
• Built-in grinding aid reduces heat buildup during stainless steel grinding
• Heavyweight polyester cloth backing supports high-pressure applications
• Resin bond construction resists heat deterioration for extended belt life
• Compatible with dry grinding or lubricated wet operation
• Produces more finished parts per belt, reducing changeover frequency in production environments

Compatibility

Designed for use on large-format belt grinders and wide-platen grinding machines that accept belts measuring 168 inches in length and 18 inches in width.

Installation Notes

Belt installation and tensioning should be performed by qualified metalworking or fabrication personnel following the equipment manufacturer's guidelines. Confirm belt grinder is fully de-energized and locked out before mounting or removing the belt. Inspect the belt for nicks, tears, or edge damage before each use, and do not exceed the machine's maximum rated belt speed. Run-in the belt at reduced pressure for the first few passes to seat the abrasive grain and check tracking alignment.
