Long lasting without loss of performance, 3M™ Cubitron™ II Cut Off Wheel efficiently cuts through even the toughest metal giving you better control while operating and over results. This rigid, reinforced resin bonded cut off wheel features 3M Precision Shaped Grain. When compared with traditional aluminum oxide, zirconia, or ceramic grain, 3M™ Cubitron™ II Abrasives cut faster and last significantly longer. And, they require less pressure and less effort on the part of the operator to do the work. Consistently faster cutting reduces cycle times. Less pressure means less wear and tear on the operator and cooler cutting action reduces the risk of heat related stress and thermal damage. It all adds up to greater productivity. 3M™ Cubitron™ II Abrasives feature 3M Precision Shaped Grain (PSG) technology, which allows 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: 3M™ Cubitron™ II cuts 30% faster and lasts 2x longer than conventional ceramic abrasives.
