  • General Features

By using nano-polycrystalline diamond for the cutting edge, these tools achieve

excellent wear resistance and fracture resistance compared to tools made with

previous polycrystalline diamond.

In particular, nano-polycrystalline diamond makes it possible to achieve improved

machining accuracy and long tool life for machining brittle materials such as carbide, etc.

  • Characteristics
  • Best suited for high precision machining of carbide Achieves high precision machining of carbide with nano-polycrystalline diamond, which has excellent wear resistance.
  • Maintain excellent dimensional accuracy over long periods Greatly reduces the number of times that the tool must be replaced compared to previous diamond tools, improving work efficiency and reducing total cost.
  • Applicable to machining brittle materials Makes it possible to perform turning on brittle materials (ceramics, etc.) that could previously only be machined through grinding.
