Cubitron II Premium Abrasive for Stainless and Mild Steels
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.
Suitable for use on all metals, stone, masonry, tiles, PVC, etc.
