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.
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.
- Corrected thread profile for avoidance of profile distortions.
- increased number of cutting edges
- new coating for optimum wear resistance
Advantage:
Incorporating a countersink profile for a 90° countersink and thread milling in a single operation.
Application:
For UNF unified fine threads ASME-B1.1.
