3M 7100025432 Abrasive Belt 40 Grit 10.688x3 Inch

Product Description

The 3M 7100025432 is a coated abrasive belt designed for aggressive stock removal and metal finishing on grinding and finishing equipment. It combines 3M ceramic abrasive grain with aluminum oxide in a blend that cuts faster and lasts longer than traditional aluminum oxide belts. The heavyweight polyester cloth backing handles high-pressure applications and can be run dry or with a lubricant. A built-in grinding aid reduces heat buildup, making this belt well suited for work on heat-sensitive metals including stainless steel. Fabricators, welders, and metal finishing technicians are the primary users.

This belt is used in industrial and fabrication shop environments for grinding, blending, and finishing on ferrous and non-ferrous metals. Its 40-grit rating positions it as a heavy stock-removal tool, appropriate for weld seam grinding, surface prep, and deburring operations. The belt can be run on standard belt grinders and finishing machines that accept a 10.688-inch by 3-inch belt. It performs consistently in both wet and dry setups, giving operators flexibility when working with lubricants or coolants.

Compatibility

Designed for use on belt grinders and finishing machines that accept a 10.688-inch by 3-inch abrasive belt in metal stock removal and finishing applications.

Installation Notes

Belt installation and replacement should be performed by a qualified operator following the belt grinder manufacturer's guidelines. Power down and de-energize the machine fully before changing the belt. Verify belt tracking and tension before resuming operation. Always wear appropriate PPE including eye protection and gloves when handling abrasive belts and operating grinding equipment.
