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

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

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

TC620 Supreme thread milling cutter – less cutting pressure, greater productivity. - Low cost per thread thanks to fast machining time and high tool life quantity - High level of process reliability and easy handling due to extremely infrequent radius correction - Very good results even under unfavourable conditions and difficult materials TC685 Supreme thread milling cutter – hard machining squared: Core hole and thread in one operation. - Cost-effective even for small and medium batch sizes - Can be used in all formable materials - Reduced torque and longer tool life thanks to new geometry and post-treatment TC410 Advance thread former – even more powerful thanks to its new geometry. - Cost-effective even for small and medium batch sizes - Can be used in all formable materials - Reduced torque and longer tool life thanks to new geometry and post-treatment
