Description
Version:
The latest generation of high-performance fluteless taps, specially developed for use in steel materials.
DIN 2174 (≈ DIN 371 ≤ 3/8; ≈ DIN 376 ≥ 7/16).
Form E (lead-in 1.5 – 2 turns). For deep threads with short lead-in. The thread is tapped almost to the bottom of the hole.
- Optimised polygon geometry for a lower torque.
- Multi-layer HIPIMS coating for high wear resistance.
- HSS-E-PM substrate for exceptional process reliability.
