  Diamond internal bar

  TRUSCO NAKAYAMA

  [Features]· Shank diameters of 3 mm.· Knoop hardness is about 7,000 (the hardest material on earth) so it can be used for most workpieces such as metals, marble, glass, etc. Most suited for workpieces with high hardness such as ceramic materials. However, since diamond does not withstand heat, it is not suitable for machining that involves production of large amounts of heat (HSS, etc.).[Applications]· Applicable workpiece materials: Carbide alloy, glass, ceramic, rubber, plastic, stone, concrete, ferrite and other nonferrous metals.
