3M Cubitron III Roughing Disc

The 3M™ Cubitron™ 3 roughing disc was developed for the toughest grinding jobs—from removing massive weld seams to demanding applications on stainless steel, structural steel, and aerospace alloys. It delivers impressive material removal rates, long service life, and reliable results even under difficult conditions.

The redesigned 3M precision grain with special bonding technology ensures that the grains continuously break during grinding, constantly forming new, sharp cutting edges. As a result, the wheel cuts faster, runs cooler, and lasts significantly longer. In a direct comparison with the 3M™ Cubitron™ II series, it removes up to twice as much material and offers a 14% higher removal rate—with reduced pressure and fewer tool changes.

Thanks to its recessed center, the roughing disc is suitable for grinding work at various angles. When used with high-performance 3M angle grinders, it delivers its full potential, making it a reliable tool for industrial applications.
