3M Cubitron III Roughing Disc

The 3M™ Cubitron™ 3 roughing disc is the right choice for particularly tough grinding tasks such as removing weld seams or working on stainless steel, structural steel, and high-strength alloys. It delivers high removal rates, reduces working time, and ensures a clean finish even under demanding conditions.

The innovative third-generation 3M Precision Grain continuously breaks into new, sharp edges during grinding. As a result, the disc works faster, stays cool during use, and wears down evenly—significantly extending its service life. Compared to Cubitron™ II abrasives, it removes up to twice as much material at speeds up to 14% higher.

Thanks to its recessed center, the disc can be used for various grinding angles. When paired with high-performance 3M angle grinders, it unleashes its full potential, enabling efficient, precise, and long-lasting work.
