HARVI™ Ultra 8X • Helical Mill • IC 12 • Taper Flange Mount

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.

HARVI Ultra 8x Taper Flange Adapters achieve maximum tool stiffness and maximum tool life.

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).
