3M 7000120309 Abrasive Belt 60x37 Inch Ao Polyester

Product Description

The 3M 7000120309 is a Trizact 253FA abrasive belt engineered for flat finishing and centerless grinding applications. It uses microreplicated aluminum oxide mineral bonded with resin onto an XF-weight polyester cloth backing that is waterproof and built to handle demanding wet finishing environments. At 60 inches long and 37 inches wide, this belt suits wide-format grinding and finishing operations in metalworking shops and fabrication facilities. Licensed trades and skilled operators in metal fabrication install and run this belt on appropriate machinery for intermediate and fine surface finishing.

This belt is designed for wet intermediate and fine finishing on a range of metals. Suitable applications include work on stainless steel, carbon steel, aluminum, nickel alloys, cobalt steel, copper, and brass. The microreplicated mineral structure delivers consistent cut rate and surface finish, reducing the risk of uneven results across the workpiece. Flat finishing and centerless operations are the primary use cases, making this belt a practical choice for production metalworking environments where consistent finish quality is required across high volumes of parts.
