    Features and benefits

    • HARVI Ultra 8X helical milling cutters are designed to deliver the highest metal removal rates (MRR), especially in high-temperature alloys.

    • Large helix ensures hassle-free chip evacuation even at highest metal removal rates (MRR).

    • Harvi Ultra 8X cutters with different lead row pocket designs available. Especially for applications that require larger corner radii.

    • Up to 8 cutting edges per insert. That's helical milling at the lowest possible cost-per-edge.

    • HU8X… cutters accommodate inserts in the lead row with corner radii from .031–.094″ (0,8–2,4mm).

    • HU8X…..R cutters accommodate inserts in the lead row with corner radii from .125–.250″ (3,2–6,4mm).
