3M 7010326987 Abrasive Belt 132x3 Inch 40 Grit Alumina Zirconia

Product Description

The 3M 7010326987 is an alumina zirconia coated abrasive belt engineered for high-production grinding and finishing applications where standard aluminum oxide belts fall short. Built on a heavyweight, water-resistant polyester cloth backing, this belt handles aggressive edge work and high-pressure contact without breaking down. The alumina zirconia grain is paired with a grinding aid that reduces heat buildup, allowing the belt to run cooler and extend usable life on heat-sensitive metals. At 132 inches long and 3 inches wide with a 40-grit cut rating, it is sized for wide-platen and long-stroke belt grinding machines common in fabrication and metalworking shops.

This belt is suited for professional use in metal fabrication, weld grinding, and surface conditioning on ferrous and non-ferrous substrates. The 40-grit designation places it in the aggressive stock-removal range, making it appropriate for initial weld seam blending, deburring, and heavy scale removal. It performs reliably on aluminum, stainless steel, mild steel, and similarly demanding materials. Machinists, fabricators, and industrial maintenance technicians are the primary installers and operators of this product.

Key Features

• Alumina zirconia abrasive grain with grinding aid delivers greater cutting efficiency than standard aluminum oxide
• Heavyweight polyester cloth backing resists water and withstands high-pressure grinding contact
• Runs cool, reducing risk of heat damage on aluminum, stainless steel, and other heat-sensitive metals
• 40-grit rating provides aggressive stock removal for weld blending, deburring, and scale removal
• 132 inch length and 3 inch width suit wide-platen and long-stroke belt grinder configurations

Compatibility

Designed for use on belt grinders and finishing machines that accept 132-inch by 3-inch abrasive belts in coated cloth form.

Installation Notes

Belt installation should be performed by the machine operator following the grinder manufacturer's belt-change procedure. Confirm the machine is fully de-energized and at a complete stop before removing or installing the belt. Verify tracking adjustment after installation and run briefly at reduced feed before returning to full production pressure. Inspect the belt for tears or delamination before each use.
