The 3M™ Cubitron™ II Cut-Off Wheel 33456 delivers extremely fast, high-precision cutting thanks to Cubitron™ II technology. These long-lasting cut-off wheels deliver a 30% faster cut and double the life of other premium abrasives. Slice through tough materials fast with less wear and tear, and help get faster, cooler, more uniform cutting on mild to high-strength steel. This 3-inch, durable wheel is engineered with 3M™ Precision-Shaped Grain (PSG) technology, where the grains self-fracture as they cut, maintaining sharp edges and extending the life of the wheel. Cutting through auto body panels, frame rails, clamps, rusted bolts, and exhaust pipes is faster and more efficient with the 3M™ Cubitron™ II Cut-Off Wheel.
