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