    Anything extra you need to know

  • Built with diamond mineral and a low-stretch backing, the 3M? Flexible Diamond Belt 6451J is a smart choice for use on hard-to-grind surfaces including thermal sprays, carbides, composites, chilled iron, non-ferrous metals, and glass
  • The open dot pattern on each 3M? Flexible Diamond Abrasive Product means that the diamond mineral particles adhere to the backing in a series of small dots
  • This is designed to provide aggressive cutting action while also allowing consistent space for evacuation of stock particles during use, helping reduce loading and prolonging the life of the abrasive surface without sacrificing cut rates
  • The 3M? Flexible Diamond Belt 6451J is available in three open dot patterns for a range of uses
  • Pattern 18 is a small dot pattern equating to 25 pellets per inch
  • The B2 Pattern has medium dots with 17 pellets per inch, and is designed to deliver an aggressive cutting action with improved coolant flow and increased swarf removal
  • Pattern 21 is offered for grades 250? and 300? only
  • It utilizes larger dots to assist in applications where high stock removal is required and loading is an issue
  • Generally, the smaller dot patterns will be the least aggressive and produce finer finishes, whereas the larger dot patterns will be more aggressive for stock removal.
  • What makes this product special

  • Excellent for hard-to-grind materials
  • Diamond mineral abrasive provides fast, consistent cut
  • Strong, low-stretch backing adds strength and resists stretching
  • Open dot construction helps minimize loading and prolonging abrasive service life
  • We suggest you should use it for:

  • Designed for roll grinding and other wet grinding and finishing applications where the abrasive is supported by a contact wheel, including file belt hand tools
  • Can be used on thermal sprays, carbides, composites, chilled iron, non-ferrous metals, glass and other hard-to-grind materials
