NTK SS tool series, TB tools, for back turning with indexable inserts can replace the conventional brazed tool which were popular for automatic lathes and Swiss type screw machine.

  • Shank size from 8mm to 25mm
  • 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.
  • Clamping of inserts assures rigidity especially when deep cutting is desired.
  • The insert grade type is selected from micro grain barbides KM3, ZM3, VM1, and cermet which ensure both sharp cutting performance and toughness.
    KM3, ZM3 or VM1 are applicable for machining that requires a sharp cutting.
    Cermet grade offers high speed cutting performance and excellent surface finish.
