Chipless Thread Repair

Full recovery of damaged threads through forming procedure

Chipless Thread Repair with Thread Savers

Thread Repair Process with Cutting Procedures

  • material is removed so the thread is workable again 
  • the static and dynamic strenght are weakened due to material loss
  • some tools damage the groove of the thread and thereby increase the notch effect (weakening of thread)
  • safety relevant parts need to be replaced
  • downtime


all our tools cover a large diameter range

A set of rollers with a pitch of e.g. 1.5mm can be used within the entire range of the tool (e.g. 50-110mm).

To cover that range for standard threads we would require at least 27 threading dies.
