Description
Version:
High-performance tap, specially developed for good process reliability in stainless and acid-resistant steels and duplex materials.
The 45° helix angle of the flutes facilitates chip formation especially in ductile austenitic CrNi steels.
The 45° helix angle of the flutes facilitates chip formation especially in ductile austenitic CrNi steels.
- HSS-E-PM tool material for maximum wear resistance
- The latest generation of TiALN multi-layer coating
- Parameterised flute geometry for optimum chip formation and rigidity
Application:
For UNF uniform fine threads ASME − B1.1.
