3M 7010308378 Abrasive Belt 36x2 Inch 80 Grit Alumina Zirconia

Product Description

The 3M 7010308378 is an alumina zirconia coated abrasive belt designed for high-production grinding, blending, and finishing on metal and other substrates. Measuring 36 inches in length and 2 inches in width with an 80-grit cut rating, this belt delivers faster stock removal than standard aluminum oxide belts. A grinding aid integrated into the mineral helps reduce heat buildup, making it well suited for work on heat-sensitive metals such as aluminum and stainless steel. The heavyweight polyester cloth backing resists moisture and holds up under high-pressure belt sander applications and aggressive edge work. It is installed and used by metal fabricators, welders, and maintenance technicians.

This belt fits stationary and portable belt sanders used in metal fabrication shops, maintenance and repair operations, and general industrial production environments. The 36-inch by 2-inch format is a common size for bench-top and inline belt grinding machines. The 80-grit designation places it in the medium-coarse range, appropriate for weld blending, surface conditioning, and rapid material removal before finishing passes. Its alumina zirconia grain performs reliably on mild steel, stainless steel, aluminum, and other hard metals.

Key Features

• Alumina zirconia abrasive grain with grinding aid cuts faster than aluminum oxide on metal
• Runs cool, reducing heat distortion risk on aluminum and stainless steel
• Heavyweight water-resistant polyester cloth backing handles high-pressure applications and edge work
• 80-grit rating suited for weld blending, stock removal, and surface conditioning
• 36 inch by 2 inch format fits common bench and inline belt grinding machines

Compatibility

Designed as an OEM-style replacement coated abrasive belt for 36 inch by 2 inch belt sanders and grinders used in metal fabrication and industrial maintenance applications.

Installation Notes

Coated abrasive belts of this type are installed by metal fabricators and maintenance technicians on compatible belt sanders or grinders. Power down and lock out the machine before changing belts. Confirm the belt tracking direction arrow aligns with the machine drive direction before startup. Inspect the platen and contact wheel for wear before mounting a new belt.
