Speed, Long Life and Ease of Use
Engineered for faster cutting, sustained performance, durability and increased throughout, our 3Mâ„¢ Cubitronâ„¢ II Abrasive Fibre Discs is a game changer. It is constructed with 3M’s breakthrough Precision Shaped Grain, with vulcanized fiber backing that resists wear and easily handles tough grinding applications like high-pressure weld grinding.
In short, Cubitronâ„¢ II outcuts and outlasts conventional ceramic industrial abrasives and requires less grinding force to achieve superior performance.
About 3Mâ„¢ Cubitronâ„¢ 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.
