3M Flexible Diamond Sheet 6450J features micron-graded diamond particles which are metal bonded to a strong yet flexible Type C backing for applications requiring flexibility. Two available open dot patterns allow for different requirements of stock removal and surface finishes. Sheet 6450J is suitable for hard-to-grind materials such as stone, glass, ceramic, carbide and composites.

Designed for Grinding Jobs Requiring a Balance of Strength and Flexibility
Combining the strength of a diamond abrasive and a semi-flexible (Type C) water resistant cloth backing, our 3M Flexible Diamond Sheet 6450J is built for achieving refined finishes to hard surfaces. It is available in a range of grades for a variety of uses.

Built Tough, Finishes Fine
We adhere the diamond mineral abrasive on 3M Flexible Diamond Sheet 6450J using a metal bond. Compared to resin or vitrified bonds, metal bonds tend to be the most tough — helping to strengthen the abrasive sheet and make it more durable. The abrasive characteristics combined with a water-resistant Type C cloth backing create an abrasive that works well on a variety of hard-to-grind materials.

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 Sheet 6450J 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. It provides consistent stock removal on very hard materials such as thermal spray coatings and ceramics. The B2 Pattern, equating to 17 pellets per inch, is designed to deliver an aggressive cutting action with improved coolant flow and increased swarf removal.
