Make Light Work of Tough Tasks with Cubitron II Ideal for tough detail work like cleaning, deburring, blending, and finishing, as well as working in small confined spaces, 3M Cubitron II File Belt 786F is available in three grades, widths and lengths. 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.

About 3M Cubitron II and Precision-Shaped Grain 3M Cubitron II abrasive discs, cutoff wheels, and file belts have raised the bar for high-performing abrasives. Cubitron abrasives feature our 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% faster and lasts 2x longer than conventional ceramic abrasives.

An Alternative to Spot Weld Drilling The 3M File Belt Sander and 3M Cubitron II File Belt 786F are a great addition to body shop tool rooms. They are a vastly superior alternative to spot weld drilling. In addition, a traditional spot weld drill goes back on the shelf. 3M's versatile file belt tool can also be used for other jobs:

• Clean and prep brake caliper pockets: Removing rust, brake dust, and other contaminants with wire brushes, files, and other tools can be tedious and time-consuming. The 3M file belt system speeds up tough cleaning jobs like this, while giving you more control to prevent gouging.
• Clean wheel rims: Removing corrosion prior to mounting the tire is critical to avoid bead leaks. The 3M file belt system makes this job quick and easy, and it is also ideal for prepping surfaces prior to attaching stick-on wheel weights and prepping centering hubs.
• Prep steering knuckles: Steering knuckle housing and mating surfaces need to be free of corrosion and other contaminants to ensure proper installation of the wheel bearing hub assembly. The 3M file belt system lets you get into deep indentations and complex surfaces, making cleanup fast and easy.
