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.
- 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 UNC uniform coarse threads ASME − B1.1.
