3M 7010308881 Abrasive Belt 36 Grit 18x3/4 Inch

Product Description

The 3M 7010308881 is an alumina zirconia coated abrasive belt designed for high-stock-removal grinding and finishing applications where standard aluminum oxide belts fall short. The 577F grade uses alumina zirconia grain with a built-in grinding aid that increases cutting efficiency while running cooler than conventional abrasives. A heavyweight, water-resistant polyester cloth backing supports high-pressure contact and edge work without delaminating or stretching. This belt measures 18 inches in length by 3/4 inch in width and is graded at 36 grit for aggressive material removal. It is installed by metal fabricators, weld grinders, and shop technicians on portable belt grinders and stationary finishing equipment.

This belt is suited for use on ferrous metals, stainless steel, aluminum, and other heat-sensitive substrates where maintaining surface integrity matters. The 36-grit designation makes it appropriate for initial weld blending, deburring, and heavy stock removal in production and job-shop environments. Its narrow 3/4-inch width fits standard portable file belt grinders commonly used for contour grinding, pipe work, and tight-radius applications. The cool-cutting characteristic of the alumina zirconia mineral reduces heat buildup, which is especially important when working aluminum or thin-gauge stainless steel.

Key Features

• Alumina zirconia grain with grinding aid cuts faster and cooler than aluminum oxide
• Heavyweight water-resistant polyester cloth backing withstands high-pressure and edge grinding
• 36 grit for aggressive stock removal, weld blending, and deburring
• Cool-running mineral reduces heat damage on aluminum and stainless steel
• Narrow 3/4-inch width suits portable file belt grinders and contour work

Compatibility

Designed as a direct-fit replacement belt for portable and stationary belt grinders accepting an 18-inch by 3/4-inch abrasive belt.

Installation Notes

Installation is performed by metal fabricators and grinding technicians. Disconnect or power down the grinder before changing the belt and confirm belt tracking before resuming operation. Ensure belt direction arrows, if present, align with the machine drive direction. Wear appropriate PPE including eye protection and gloves during belt changes and grinding operations.
