Ferg produce a wide range of threading taps in HSS and in tungsten carbide for solve the complex threading of the heat-treatable steels and high resistance steels:
- Machine tap HR: for threading high resistance steels, 1300 N/mm2
- Machine tap HR+ : for threading hardened steels 40 ÷ 63 Hrc.
The range that FERG has as standard can be used for different materials and hardness at also produces specials applications adapted to the requirements of the costumers.
