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

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 edge 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 edge life
