The Walter Prototyp Paradur® Eco CI is an HSS-E-PM machine tap for both blind and through hole threads that is suitable for machining cast iron and short-chipping aluminium.

Facts and advantages:

  • optimum wear resistance thanks to new type of Xtra•treat™ surface treatment
  • short chips due to low rake angle and increased number of flutes
  • graded TiCN multilayer coating for high cutting speeds and long tool life
  • versions available with axial or radial coolant exit for optimum chip transport when creating deep blind and through hole threads
  • reduced production costs per thread due to high cutting speeds and long tool life
