The range of NTK SS tools for cut-off are available with widths of 3mm or less. They can meet all sorts of cut-off operations especially for
small parts.

  • Indexable insert toolholders for cut-off applications with shank sizes ranging from 8mm to 25mm, which eliminated re-griding.
  • Can be adjusted for almost all CNC automatic lathes or small type CNC lathes.
    The shape of tools are selectable for gang tooling type tool post or turret type tool post.
  • The cut-off widths range from 0.7mm to 3.0mm.
  • The shape of the cutting edge keeps the centre boss to a minimum.
    The larger lead angle of the cutting edge, sharp corner radius, and precise centre position control eliminates the centre boss.
  • Micro grain carbides KM3, ZM3, QM3 and VM1, which provide both excellent sharp cutting performance and toughness, are used. These materials guarantee stable and long tool life.
