Designed for Light Pressure Grinding on Contoured Surfaces

Combining the strength of a hard mineral abrasive with a very flexible conformable backing, the 3M Flexible Diamond Roll 6457J is specifically designed to achieve a wide range of finishes. This diamond abrasive roll is ideal for use on challenging surfaces such as thermal sprays, carbides, composites, chilled iron, non-ferrous metals, and glass.

Built Tough, Finishes Fine

3M utilizes a metal bond to secure the diamond mineral particles on the 3M Flexible Diamond 6457J. Metal bonds are known for their exceptional toughness, which enhances the durability of the diamond abrasive. The VF cloth backing of this product is particularly effective for grinding complex geometries.

Open Dot Pattern: What Does it Mean?

The open dot pattern found on each 3M Flexible Diamond abrasive product indicates that the diamond mineral particles are adhered to the backing in a series of small dots. This design allows for aggressive cutting action while ensuring consistent space for the evacuation of stock particles during use. As a result, it helps reduce loading and extends the life of the abrasive surface without compromising cut rates.

The 3M Flexible Diamond Belt 6457J is available in two open dot patterns to cater to various applications. Pattern 18 features a small dot pattern with 25 pellets per inch, while the B2 Pattern has medium dots with 17 pellets per inch. The B2 Pattern is specifically designed to deliver aggressive cutting action, improved coolant flow, and increased swarf removal. Generally, smaller dot patterns are less aggressive and produce finer finishes, while larger dot patterns are more effective for stock removal.
