RVG® Diamond High Friability

Hyperion Materials & Technologies manufactures the RVG 810 and RVG 800 series diamonds that are highly friable crystals.  These man-made or synthetic diamonds are available as uncoated or coated. Additional information is provided below:


RVG 810 Series


RVG 810 Diamond


RVG 810 diamond is ideal for high precision grinding in demanding materials with stringent quality requirements. RVG 810 diamond is extremely effective where wheel life and/or form retention are critical.


RVG 810D Diamond

Copper-based alloy coating [coating level 50 wt %]

RVG 810D diamond is a highly friable crystal with Cu coating for ideal performance in dry phenolic or wet polyimide grinding of carbides and polycrystalline diamond (PCD).


RVG 890 Diamond

Nickel-based alloy coating [coating level 56 wt %]

RVG 890 diamond is the most productive crystal in the RVG diamond family. It boasts excellent free cutting characteristics and controlled micro fracturing mode while providing superior surface finishes. RVG 890 diamond is unparalleled in part-to-part consistency when it comes to technical ceramics, CERMETS, and new hard-to-grind materials.



RVG 800 Series


RVG 800 Diamond


RVG 800 diamond offers superior free cutting capabilities due to the controlled microfracturing of the crystals. It is suitable for applications with demanding tolerance requirements. Consistent finishes and accurate geometries are achieved in grinding of tungsten carbides, new materials, CERMETS, and technical ceramics.


RVG 880 Diamond

Nickel-based alloy coating [coating level 56 wt %]

RVG 880 diamond offers even more improved free cutting and fracture characteristics, provides extended wheel life, and requires low grinding power. Textured coating enhances crystal retention while extracting heat from the grinding interface. This diamond is highly suitable for wet grinding of cemented carbide and ceramic workpieces.
