The Walter Prototyp Protodyn® (S) Plus is a thread former for general applications with an even longer tool life. The version with lubrication grooves is also ideal for thread depths of up to 3.5 x d. Overall, this is a universal HSS-E thread former for use with all ductile materials.

Facts and advantages:

  • optimised polygonal form reduces friction and thereby increases tool life
  • high degree of process reliability, even for deep blind hole and through hole threads, thanks to the non-chipping thread production process
  • maximum machining reliability, particularly for small dimensions, thanks to stable tool geometry
  • reduction in tool diversity, since the one tool can be used universally in a wide range of materials, as well as for blind hole and through hole threads
  • high degree of dynamic tensile strength of the formed thread thanks to cold work hardening of the thread flanks and thread root

  • available with and without lubrication grooves
