3M's highest quality, top-of-the-line cut-off wheel, this wheel is made using the breakthrough Cubitron II abrasive.
Cubitron II makes for ultra-fast, cool cutting action, and longer life compared to other cut-off wheels.
These wheels are specially formulated to be used on stainless and mild steels.
Cubitron II is a revolutionary 3M™ precision-shaped ceramic grain technology.
It is engineered with mineral crystals that are sharp-edged, fast-cutting, and shaped like pyramids which are electrostatically oriented so they point upwards - like sharp peaks. The peaks act like individual cutting tools - slicing through metal, wearing evenly, running cooler, and providing super-long life and cutting consistency.
Mineral breakdown is optimized because, instead of getting rounded as they wear, the pyramids continuously fracture to form brand new, sharp, cutting edges — maximizing performance and wheel life.
By contrast, conventional ceramic abrasive grain is irregular in shape. Instead of a clean slicing action, the grain "plows" through the metal, causing heat build up, slower cutting, and shorter life. See illustration at left.
