3M 7010308374 577F Abrasive Belt 90x6 Inch 40 Grit

Product Description

The 3M 7010308374 is the 577F coated abrasive belt, built for high-pressure grinding and edge work where standard aluminum oxide belts fall short. The abrasive grain is alumina zirconia with a grinding aid, which delivers faster cut rates and cooler running temperatures than conventional aluminum oxide. The belt measures 90 inches long by 6 inches wide and carries a 40-grit rating. A heavyweight, water-resistant polyester cloth backing supports demanding production environments without breaking down under load. Metal fabricators, weld shops, and industrial maintenance technicians are the primary installers and users of this product.

This belt is suited for high-production grinding, blending, and edge finishing on metal substrates. The cooler-running alumina zirconia grain makes it particularly effective on heat-sensitive metals such as aluminum and stainless steel, where excessive heat can cause discoloration, warping, or work hardening. The heavyweight cloth backing holds up during aggressive stock removal as well as finer finishing passes. It is sold individually and is appropriate for use on wide belt sanders and grinders configured for 90-inch by 6-inch belts.

Key Features

• Alumina zirconia grain with grinding aid cuts faster than aluminum oxide on metal
• Runs cool, reducing heat-related damage on aluminum and stainless steel
• Heavyweight water-resistant polyester cloth backing withstands high-pressure applications
• 40-grit rating suited for aggressive stock removal and surface conditioning
• 90 inch by 6 inch format fits wide belt sanders and industrial grinders

Compatibility

Designed for use on wide belt sanders and grinders that accept a 90-inch by 6-inch abrasive belt. Suitable for grinding and finishing applications on metal, including aluminum and stainless steel.

Installation Notes

Belt installation should be performed by a qualified operator following the machine manufacturer's guidelines for belt tracking and tension. Ensure the sander or grinder is fully powered down and locked out before changing belts. Inspect the belt for tears or splice damage before mounting. Confirm belt direction arrows align with the machine's drive direction where indicated.
