• roll shear knives are made of different materials.
  • Made from forged tool steels, high-speed steels, Neuenkamp's special materials and powder-metallurgically produced high-performance steels.
  • The roll shear knives are heat-treated in process-controlled hardening plants.
  • The material and hardness are matched to the respective application.

Carbide knives:

  • Carbide knives are made of are made from sintered hard metal powder and hot isotonic post-compacted (HIP).
  • The particular composition and core size of the knives depends on the application.


  • Standard tolerances of +/- 0.001 mm
  • Ultra-precision tolerances of +/- 0.0005 mm
