3M 7100109881 Abrasive Belt 132x4 in P100 Grit Ao Ceramic

Product Description

The 3M 7100109881 is a coated abrasive belt designed for demanding stock removal and metal finishing applications. It combines 3M Ceramic Abrasive Grain with aluminum oxide in a blend that cuts faster and lasts longer than standard aluminum oxide belts. The heavyweight polyester cloth backing is rated for high-pressure grinding and can be run dry or with lubricant. At 132 inches long and 4 inches wide with a P100 grit rating, this belt is sized for industrial-grade belt grinders used in fabrication and finishing operations. A built-in grinding aid reduces heat buildup, making it well-suited for heat-sensitive metals including stainless steel.

This belt is intended for use in metal fabrication shops, weld grinding, and surface finishing workflows where high material removal rates and consistent finish quality are required. It performs well on stainless steel, carbon steel, and other metals where heat generation is a concern. The orange-colored belt is a standard color code for this product line and aids in quick belt identification during job changes. It is commonly installed and used by machinists, fabricators, and metal finishing technicians working with wide-belt and contact-wheel grinders.
