Red Ring Taps are designed to cut threads in High Resistant steels. For very tough materials over 1000 N/mm*.

Blue Ring Taps are designed for tough stainless steels and high alloyed tool steels which have a tendency to "close" after threading. For stainless steels.

Green Ring Taps are designed for tough non ferrous metals which have a tendency to "close" after threading. Eg Bronze or Alu with Si>10%. For tough non ferrous metals.

White Ring Taps have a modified rake angle. 15° lead and nitride surface treatment. For cast iron and other abrasive short chipping materials. Not listed as standard please enquire.
