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 cutting action and long tool life. 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.
- Latest-generation AlTiN-based HIPIMS coating.
- Corrected thread profile for avoidance of profile distortions.
Advantage:
Significantly less radial pressure than with multi-tooth thread mills. Axial cooling grooves on the shank for optimum chip evacuation.
Application:
For Whitworth parallel pipe threads DIN-ISO 228/1 (threads that do not form a seal within the connections). Suitable for internal and external threads.
Note:
HB and HE shanks are available at the same price as HA.
HB shank: order with No. 139631 + 129100 HB.
HE shank: order with No. 139631 + 129100 HE.
HB shank: order with No. 139631 + 129100 HB.
HE shank: order with No. 139631 + 129100 HE.
Can also be used for thread size G3/8
