Designed for fine finish sanding of contours on hard-to-grind materials, 3M Flexible Diamond Belt 6457J is ideal for light pressure grinding. Metal bonding of the diamond abrasive to the backing ensures durability, while the open dot pattern reduces loading.
VF Backing Excels at Light Pressure Grinding on Contoured Surfaces
Combining the strength of a hard mineral abrasive with a very flexible conformable backing, our 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.
Built Tough, Finishes Fine
We fasten the diamond mineral particles on 3M Flexible Diamond 6457J using a metal bond. Compared to resin or vitrified bonds, metal bonds tend to be the most tough — helping to strengthen the diamond abrasive and make it more durable.. This VF cloth backing works very well for complicated geometries.
Our Open Dot Pattern: What Does it Mean?
The open dot pattern on each 3M Flexible Diamond abrasive product means that the diamond mineral particles are adhered 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.
3M Flexible Diamond Belt 6457J is available in two open dot patterns for a range of uses. Pattern 18 is a small dot pattern equating to 25 pellets per inch Our 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. 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.
