3M™ Cubitron™ II File Belt is a premium abrasive file belt for spot weld removal and other grinding or sanding applications. This file belt can be used with various types of file belt sanding machines available in the market. Ideal for tough detail work like cleaning, deburring, blending and finishing as well as working in small confined spaces. The exceptionally fast cut and long life of 3M™ ceramic abrasive grain enable this slim belt to accomplish a remarkable degree of work. Its fast cutting action helps eliminate burning or other forms of thermal damage, as well. 3M™ Cubitron™ II abrasive discs, cutoff wheels and file belts have raised the bar for high-performing abrasives. Cubitron™ abrasives feature Precision-Shaped Grain PSG technology, which allows our engineers to control the geometry of the abrasive grain for a truly fast, efficient cut. Instead of simply crushing the abrasive into particles, 3M uses microreplication to uniformly size ceramic grains and precisely shape them into triangular structures — essentially, sharp peaks that slice, not plow, through paint and metal. These grains are electrostatically oriented on the abrasive surface for the most efficient cut and even wear. What's more, PSG fractures during use to maintain sharp abrasive edges. The result: Cubitron™ II cuts 30 Percent faster and lasts 2x longer than conventional ceramic abrasives.
