20.00mm Dia, 4 Flute, Corner Radius End Mill - 42717

SERIES: ZH1M

Z-Carb-HTA

20.00mm Dia, 26.00mm LOC, 20.00mm Shank Dia, 1.00mm Radius, 4 Flute, 38-41 Degree Helix, Ti-NAMITE-A (AlTiN) Coated, Series ZH1M, Z-Carb-HTA, Corner Radius End Mill - 42717

Feature & Benefits

  • The original Z-Carb design with an enhanced core and higher helix suited for the demands of high temperature alloys
  • Unequal flute spacing helps to disrupt the rhythmic pattern created by the cutting edge helping to suppress damaging harmonics
  • Optimal material removal rates through increased feed and depths of cut for difficult to machine materials
  • Enhanced corner geometry with tight tolerance corner radii
  • Recommended for materials ≤ 45 HRc (≤ 420 Bhn)
