    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.
    • 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.

    Advantage:

    Incorporating a countersink profile for a 90° countersink and thread milling in a single operation.

    Note:

    HB and HE shanks are available at the same price as HA.
    Order HB shank: with No. 139683 + 129100 HB
    Order HE shank: with No. 139683 + 129100 HE
