3M™ Cubitron™ Abrasive Grain

3M™ Cubitron™ Abrasive Grain is a chemically engineered ceramic aluminium oxide mineral with a unique “stay sharp” crystalline structure that continually reveals fresh cutting edges to the surface of the workpiece to give a sustained cut and long product life. This more durable, cost-effective abrasive solution delivers real productivity benefits across an operation without the premature dulling associated with traditional abrasives.

  • Formulated for strength and long life
  • Engineered to stay sharp
  • Designed for thermal stability

Technology Explained

With Cubitron, you get a sol gel mineral that sharpens as it wears.

  1. Initial grinding breaks away small edges of the grain.
  2. As grinding continues, micro fractures form which break off to create fresh sharp edges.
  3. This process repeats throughout the grinding operation for long-term efficiency and increased return on investment
