monobloc roll form tap / through-hole / for blind holes / straight flute

Walter Prototyp Protodyn® S Synchrospeed

The Walter Prototyp Protodyn® (S) Synchrospeed HSS-E thread former has been specifically developed for use in machines with synchronous spindles. The tool is particularly suitable for cutting threads in all ductile materials with a strength of up to 1300 N/mm² or at least 7% ultimate strain.

Facts and advantages:
- universal use (through holes and blind holes)
- long tool life through special polygonal form and synchronous machining
- high degree of process reliability thanks to short threaded part and special geometric design
- shank with h6 tolerance for shrink-fit chucks, as well as clamping surface for weldon adaptors
- greater cost efficiency thanks to special surface treatment

Protodyn® (S) Plus

Cold forming taps
Walter Prototyp Protodyn® (S) Plus

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

Cold forming taps
Walter Prototyp Protodyn® (S) HSC

The Walter Prototyp Protodyn® (S) HSC solid carbide thread former offers maximum cutting speed, coupled with maximum tool life. A new carbide substrate guarantees maximum toughness with the greatest possible wear resistance. The optimised polygonal form reduces friction and thereby increases tool life.

Facts and advantages:
- non-chipping thread production process for a high degree of process reliability, even when working with deep blind hole and through hole threads
- impressive tool life and attractive price/performance ratio
- fewer tool changes thanks to longer tool life
- high degree of dynamic tensile strength of the formed thread thanks to cold work hardening of the thread flanks and thread root
