Highlights
  • Flexible backing is ideal for contouring
  • Diamond mineral excels at cutting hard-to-grind materials
  • Metal bonding adds durability and long belt life

The 3M™ Flexible Diamond Belt 6457J is a micron-graded diamond abrasive that is metal-bonded to a flexible, water-resistant cloth backing.

Combining the strength of a hard mineral abrasive with a very flexible conformable backing, the 3M™ Flexible Diamond Belt 6457J is built for achieving a range of finishes most suitable for grinding applications requiring light pressure such as blending and finish sanding of contours. This diamond abrasive belt is built for use on hard-to-grind surfaces including thermal sprays, carbides, composites, chilled iron, non-ferrous metals, and glass. The diamond mineral particles are fastened on a 3M™ Flexible Diamond Belt 6457J using a metal bond. Metal bonds tend to be the toughest bonds, helping to strengthen the diamond abrasive and making it more durable. This VF cloth backing works very well for complicated geometries.
