20.00mm Dia, 4 Flute, Corner Radius End Mill - 42738
SERIES: ZPMC
Z-Carb-AP
20.00mm Dia, 38.00mm LOC, 52.00mm Reach, 20.00mm Shank Dia, 4.00mm Radius, 4 Flute, 35-38 Degree Helix, Ti-NAMITE-X (TX) Coated, Series ZPMC, Z-Carb-AP, Corner Radius End Mill - 42738
Feature & Benefits
- Variable rake geometry alters and controls the cutting dynamic taking chatter suppression to an unprecedented level
- Unequal helix design changes the cutting angle to improve harmonics
- Unequal flute spacing helps to disrupt the rhythmic pattern created by the cutting edge helping to suppress damaging harmonics
- Long reach design allows for deeper and faster cuts
- Enhanced corner geometry with tight tolerance corner radii
- Recommended for materials ≤ 45 HRc (≤ 420 Bhn)
