3M 7100042430 Abrasive Belt 90x4 Inch P120 Grit Ao Ceramic

Product Description

The 3M 7100042430 is a coated abrasive belt designed for stock removal and metal finishing in demanding industrial applications. It combines 3M Ceramic Abrasive Grain with aluminum oxide in a blend that cuts faster and outlasts standard aluminum oxide belts. The heavyweight polyester cloth backing supports high-pressure belt grinding and handles heat-sensitive metals without premature breakdown. Measuring 90 inches long by 4 inches wide, it fits standard contact-wheel and platen belt grinders used in fabrication and finishing shops. A built-in grinding aid reduces heat generation, making it particularly effective on stainless steel. The belt can be run dry or with a lubricant depending on the application.

This belt is suited for metal fabrication, weld blending, and surface conditioning on ferrous and non-ferrous metals. It handles applications where consistent cut rate and long belt life reduce downtime between belt changes. The P120 grit provides a medium-fine finish pass appropriate for pre-polish stages or final surface prep before coating. Fabricators, weld finishers, and metalworking shops running high-cycle grinding operations are the primary users of this product.

Key Features

• Ceramic and aluminum oxide grain blend delivers faster cut rate and longer service life than standard aluminum oxide
• Heavyweight polyester cloth backing withstands high-pressure contact-wheel and platen grinding
• Grinding aid reduces heat buildup, extending usable life when finishing stainless steel
• Durable resin bond resists heat deterioration for consistent performance over the belt life
• Can be operated dry or with lubricant depending on workpiece material and application
• P120 grit suitable for medium-fine stock removal, weld blending, and pre-polish surface prep

Compatibility

Designed for use on standard belt grinders and backstand grinders that accept 90-inch by 4-inch abrasive belts in metal fabrication and finishing applications.

Installation Notes

Belt installation should be performed with the grinder powered off and locked out per OSHA lockout/tagout procedures. Verify belt tracking and tension before resuming operation. Always confirm the belt arrow direction matches the intended direction of travel on the machine. Wear appropriate PPE including eye protection and gloves during belt changes.
