This 3M Cubitron 3 Cloth Belt is a 4 inch by 168 inch abrasive belt designed for heavy-duty grinding and stock removal. The re-engineered 3M Precision-Shaped Grain (PSG) cuts exceptionally fast and lasts a long time, meaning less time spent changing belts and more time spent working on metal fabrication or welding projects.
- It cuts significantly faster than previous generations (up to 86% faster for the 36+ grit option), which dramatically increases your daily productivity and throughput.
- The belt’s longer life helps you reduce abrasive consumption and lower your overall operating costs, making it a more economical choice over the long run.
- The Single-Flex construction with Film-Lok backing allows the belt to be run in both wet and dry applications, giving you flexibility on various grinding tasks.
Who this is best for
This belt is ideal for professionals in metal fabrication, heavy equipment manufacturing, foundries, or any industrial facility requiring efficient, high-performance stock removal on carbon steel, stainless steel, or other hard metals.
