Description
Version:
The latest generation of high-performance fluteless taps are specially developed for use in steels.
With internal coolant supply laterally from the grooves; suitable for blind and through holes.
Form E (1.5-2 threads). For threads almost to the bottom of the hole.
- Optimised polygon geometry for a reduced torque.
- Multi-layer HIPIMS coating for high wear resistance.
- Solid carbide substrate with increased Co content for good toughness and maximum process reliability.
With internal coolant supply laterally from the grooves; suitable for blind and through holes.
Form E (1.5-2 threads). For threads almost to the bottom of the hole.
Note:
DIN 2174 (≈ DIN 371 ≤ M10; ≈ DIN 376 ≥ M12).
