3M 7000119449 Abrasive Belt 577F 15.5x3.5 in 60 Grit

Product Description

The 3M 7000119449 is the 577F alumina zirconia coated abrasive belt, designed for aggressive material removal on metal and other demanding substrates. The alumina zirconia grain with grinding aid cuts faster and runs cooler than standard aluminum oxide, making it a practical choice for heat-sensitive metals such as aluminum and stainless steel. The belt measures 15.5 inches in length and 3.5 inches in width with a 60-grit cut. A heavy polyester cloth backing resists water and holds up under high-pressure belt grinding and edge work in production environments. Metal fabricators, weld prep crews, and industrial maintenance techs are the primary installers.

This belt is suited for high-production grinding, blending, and finishing operations on metal fabrication equipment. The 60-grit grade positions it for stock removal and weld seam blending rather than fine finishing. The water-resistant backing makes it appropriate for both dry and wet-process applications. Its cool-running characteristics reduce the risk of heat discoloration or warping on stainless steel and aluminum workpieces where surface integrity matters.

Key Features

• Alumina zirconia grain with grinding aid delivers faster cutting than aluminum oxide
• Runs cool, reducing heat buildup on aluminum, stainless steel, and other heat-sensitive metals
• Heavy polyester cloth backing resists water and withstands high-pressure grinding and edge work
• 60-grit cut suited for aggressive stock removal and weld seam blending
• Belt dimensions of 15.5 inches by 3.5 inches fit standard production belt grinders

Compatibility

Designed as a replacement-style coated abrasive belt for belt grinders and finishing machines that accept a 15.5-inch by 3.5-inch belt configuration.

Installation Notes

Belt installation should be performed by qualified personnel following the equipment manufacturer's guidelines. Confirm belt tension, tracking adjustment, and guard placement before starting the grinder. Power down and lock out the machine before changing belts. Inspect the belt for tears or splice defects before each use and do not exceed the machine's rated surface speed.
