Thread formers

The ECO thread former Protodyn Cap from Walter Prototyp has been developed to guarantee optimal internal coolant supply. The innovative, front face radial coolant outlets mean the tool has a higher degree of stability in comparison to conventional thread formers with internal cooling.

ECO thread former Protodyn CAP

  • Significantly increased tool life in terms of external coolant supply, particularly with greater thread depths.
  • Equally suitable for use in blind and through holes.
  • Optimised for wet machining, but minimum quantity lubrication is also possible.
  • Greater tool life due to the TIN-coating that has been specially modified for thread formers.

The HSS-E thread former PROTODYN S Synchrospeed has been specially developed for use in machines with synchronous spindle. The tool is particularly suitable for producing threads in all ductile materials with a strength of up to 1200 N/mm² or at least 10% expansion.

Synchrospeed-thread former Protodyn S Synchrospeed

  • Universal use (through holes and blind holes)
  • High tool life through HSS-E
  • High accuracy to gauge thanks to pointed polygon profile
  • High process reliability thanks to short thread component and special geometry
  • High degree of efficiency thanks to special surface treatment
