Description
Version:
Solid carbide thread milling cutters with irregular cutting edge spacing and an increased number of cutting edges. Due to the irregular cutting edge spacing they achieve very smooth running and long tool life.
Newly developed universal geometry and high-performance coating for use across a wide spectrum of materials.
Through-coolant feed ≥ M4
Newly developed universal geometry and high-performance coating for use across a wide spectrum of materials.
- Significantly reduced vibration due to irregular cutting edge spacing.
- Increased number of cutting edges.
- New coating for optimum wear resistance.
- Corrected thread profile for avoidance of profile distortions.
Through-coolant feed ≥ M4
