3M 7010309077 Abrasive Belt 80 Grit 72x3.75 Inch Cubitron Ii

Product Description

The 3M 7010309077 is a coated abrasive belt from the Cubitron II 967F series, designed for aggressive material removal on carbon steel, nickel alloys, tool steels, and titanium. It features 3M Precision Shaped Grain bonded to a heavyweight polyester backing, which allows the grain to fracture predictably and maintain sharp cutting edges throughout the belt's service life. At 72 inches long and 3.75 inches wide with an 80 grit rating, this belt is built for high-pressure grinding and off-hand applications. Licensed metalworking shops, weld prep operations, and fabrication facilities rely on this belt for consistent cut rates and extended belt life.

This belt is suited for dry off-hand grinding, weld blending, and rough stock removal on ferrous and non-ferrous metals including carbon steel, tool steels, and heat-sensitive high-nickel alloys. The integrated heat-resistant grinding aid makes it a practical choice for titanium grinding where heat buildup typically degrades conventional abrasives. It is used on wide-belt and contact-wheel belt grinders in manufacturing, aerospace fabrication, and heavy industrial applications where throughput and part yield per belt are critical metrics.

Key Features

• 3M Precision Shaped Grain fractures to maintain sharp cutting edges, reducing the number of belt changes per shift
• Heavyweight polyester backing withstands high-pressure grinding without delaminating or stretching
• Heat-resistant grinding aid enables effective rough grinding of titanium and high-nickel alloys
• 80 grit rating delivers aggressive stock removal while leaving a consistent surface finish
• Optimized for dry off-hand and contact-wheel applications on carbon steel and tool steels

Compatibility

Designed as a coated abrasive replacement belt for wide-belt grinders and contact-wheel belt grinder setups handling carbon steel, tool steels, nickel alloys, and titanium in high-pressure grinding applications.

Installation Notes

Belt installation should be performed by qualified grinding equipment operators following the machine manufacturer's belt-tracking and tensioning procedures. Disengage and lock out all power to the grinder before mounting or removing the belt. Confirm belt direction-of-travel arrow aligns with the grinder wheel rotation before startup. Personal protective equipment including face shield, gloves, and hearing protection is required during operation per applicable workplace safety standards.
