3M 7100033194 Cubitron Ii 786F File Belt 60 Grit 13x3/8 in

Product Description

The 3M 7100033194 is the Cubitron II 786F abrasive file belt, engineered for demanding metal grinding and material removal tasks in fabrication and body shop environments. Built on a heavy-duty backing with resin-bonded Precision Shaped Grain, this belt delivers fast, consistent cutting action across its full service life. The ceramic and aluminum oxide blend is precisely shaped, uniformly sized, and vertically oriented for efficient stock removal. A grinding aid keeps operating temperatures low, reducing the risk of metal discoloration, oxidation, and heat-related stress cracking on high-strength steel. Licensed tradespeople in welding, fabrication, and collision repair will find this belt particularly suited to high-output workflows.

The 786F file belt is designed for use with file belt sanders in applications including rivet grinding, spot weld removal, and contour finishing on metal surfaces. At 13 inches long and 3/8 inch wide, it fits the narrow-profile file sander format required for tight-access areas and contoured workpieces. The 60-grit rating positions it as a medium-aggressive option for rapid material removal without sacrificing surface control. This belt is sold in a minimum quantity of 5 per box, making it practical for shop stocking.
