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)
