• Sumicrystal UP cutting tool blanks are cut from large high quality single crystal diamonds which were synthesized under ultra-high pressure and temperature
• Sumicrystal blanks are classified as type 1B and all sides of the UP blank are 100 face orientation
• Sumicrystal diamond contains controlled amounts of dispersed nitrogen (10-100 ppm) which allows for very uniform blank to blank properties, superior fracture strength, high hardness and high thermal conductivity
• Special shapes and sizes (up to 7.0 mm) are available in addition to the standard blanks shown below:
