Premium High Performance Abrasive for Mild and High Strength Steels
Featuring the revolutionary Cubitron II ceramic mineral, these are 3M's top-of-the-line cut-off wheels.
The wheel's precision-shaped abrasive grains are engineered to cut faster than competitive ceramic products, thus offering significant productivity gains.
Cubitron II upward-oriented triangular shaped abrasive wears evenly, runs cooler, and optimizes mineral breakdown, for extra long life.
These rigid, reinforced resin-bonded wheels slice through almost all metals.
Outstanding cutting performance on both mild steel and ultra high-strength steel
Only use on power tools with a maximum operating speed no greater than 25,000 rpm
Do not use on tools without a proper sized guard for the size of the cut-off wheel
NOTE - This wheel must be used with an ANSI-approved flange for Type 1 cut-off wheels
Heavy on the technical side...
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 disc 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.
