Coated SUMIBORON BNC8115

  • PVD coating with excellent wear resistance suppresses flank wear in machining of exotic alloy cast iron and hardened steel
  • Ideal for roughing and 0.5mm to 0.3mm depths of cut can also be used for roughing and finishing of grey cast iron
  • Gold-colored coating for improved visibility of used corners
