3M 7100033207 Abrasive Belt 18in X 1/4in 80 Grit

Product Description

The 3M 7100033207 is an alumina zirconia coated abrasive belt designed for high-production grinding, blending, and finishing applications where standard aluminum oxide belts fall short. The belt uses an alumina zirconia mineral with a grinding aid that delivers faster cut rates and longer service life than conventional abrasives. A heavyweight, water-resistant polyester cloth backing supports high-pressure applications and edge work without breaking down prematurely. Measuring 18 inches in length and 1/4 inch in width at 80 grit, this belt suits metal fabrication shops, weld blending, and surface prep work performed by machinists, fabricators, and finishing professionals.

This belt is intended for use on a range of metallic substrates, including heat-sensitive materials such as aluminum and stainless steel. The alumina zirconia mineral runs cooler than aluminum oxide, reducing the risk of heat discoloration or material distortion during extended grinding sessions. It fits narrow-platen and file-belt machines commonly found in production finishing environments and is sold individually.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide on metal substrates
• Runs cool, making it suitable for heat-sensitive metals including aluminum and stainless steel
• Heavyweight water-resistant polyester cloth backing withstands high-pressure grinding and edge work
• 80 grit provides aggressive stock removal with a controlled surface finish
• 18 inch by 1/4 inch size fits narrow-platen and file-belt machines

Compatibility

Designed as an OEM-style replacement or direct-fit belt for narrow-platen, file-belt, and similar belt-drive abrasive machines accepting an 18 inch by 1/4 inch belt configuration.

Installation Notes

Installation should be performed by a trained machinist or finishing technician familiar with belt-drive abrasive equipment. Power down and lock out the machine before replacing the belt. Verify the belt tracking direction arrow aligns with the machine spindle rotation before resuming operation. Inspect the platen, contact wheel, and tension assembly for wear before installing a new belt.
