Q: What makes Cubitron II abrasive technology superior?
A: Cubitron II uses precision-shaped ceramic grains that are uniformly sized and triangular—designed to slice rather than plow through metal. This results in up to 30 percent faster cutting and twice the belt life compared to conventional ceramic abrasives.
Q: Can this belt be used on standard file belt sanders?
A: Yes. The 33445 belt is designed for use with 3M File Belt Sanders and is compatible with various file belt sanding machines available in the market.
Q: How does the belt reduce heat during grinding?
A: The resin bond combined with a dry grinding aid helps the belt run cooler, reducing the risk of heat-related metal discoloration, oxidation, and stress cracks—especially effective on high-strength steel.
