Excels at Light-Duty Applications on ContoursStriking a balance between strength and conformability, our versatile 3M™ Flexible Diamond Belt 6454J conforms well to contours on hard to grind materials.. It's best for lighter duty applications, such as blending and finishing contours, and it may be used on thermal sprays, carbides, composites, chilled iron, non-ferrous metals, glass and other hard-to-grind materials.Built Tough, Finishes FineWe adhere the diamond abrasive on 3M™ Flexible Diamond 6456J using a metal bond. Compared to resin or vitrified bonds, metal bonds tend to be the most tough. The backing is the most flexible backing type of our 3M™ Flexible Diamond products, which helps the abrasive respond well to surface imperfections and contours.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 swarf during sanding, helping reduce loading and prolonging the life of the abrasive surface without sacrificing cut rates.3M™ Flexible Diamond Belt 6454J 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.Recommended ApplicationsLightweight applications on backstand or benchtop sandersContour sandingFinish sandingBetter Science for Better Sanding from 3MWithin the 3M portfolio of Superabrasives, our 3M™ Flexible Diamond Belt 6454J is an outstanding example of how 3M applies science to the lives of professionals in a range of specific industries where excellent grinding and finishing are critical.
