3M 7100231548 Abrasive Belt 80 Grit 52x75 in Aluminum Oxide

Product Description

The 3M 7100231548 is a heavy-duty coated abrasive belt engineered for demanding material removal and surface finishing applications. Built on a Series 340D platform, this belt uses aluminum oxide abrasive grain bonded to an X-weight cloth backing with an open coat density. At 80 grit, it delivers medium-grade cutting action suited to aggressive stock removal, blending welds, and preparing metal or wood surfaces before finer finishing passes. The X-weight cloth backing resists tearing under tension and heat generated during high-pressure belt grinding operations, making it a reliable choice for production and maintenance environments alike.

This belt is sized at 52 inches wide by 75 inches long, placing it in the wide-format category used on large stationary belt grinders, wide stroke sanders, and industrial platen machines. It is configured for dry operation only. Typical applications include metal fabrication shops, woodworking mills, composite finishing, and heavy surface preparation work where consistent cut rate and belt life are priorities. Maintenance technicians and production floor operators handling large workpieces will find this size appropriate for high-throughput grinding tasks.

Key Features

• Aluminum oxide abrasive grain provides durable, consistent cutting action on metal, wood, and composites
• 80 grit medium grade balances aggressive stock removal with reasonable surface finish
• Open coat density reduces loading and extends belt life in resinous or soft materials
• X-weight cloth backing handles high tension and heat without delaminating
• Series 340D construction designed for dry belt grinding and sanding operations
• 52 inches x 75 inches wide-format size fits large industrial belt machines

Compatibility

Designed for use on wide-format industrial belt grinders and stroke sanders that accept 52-inch by 75-inch abrasive belts in dry operation configurations.

Installation Notes

Installation should be performed by qualified personnel familiar with the belt grinder or sander being serviced. Power down and lock out the machine completely before removing a worn belt or mounting a new one. Verify belt tracking adjustment and tension settings according to the machine manufacturer specifications before resuming operation. Inspect the contact wheel, platen, and idler for wear or damage that could cause uneven belt loading or premature failure.
