Description
4-flute high-precision finishing carbide ball end mill for high-hardness steels
Features & Benefits
- Variable Negative Spiral Gash
Controls chipping while securing cutting quality by making the negative angle weaker near the outer periphery; chipping resistance is enhanced in combination with the weaker helix angle specification
- Superior Ball R Precision
Secures stable R accuracy across 180°
- Thickness at Center
Thickening of the center core to prevent deformation of the ball tip and improve control of chipping
- Superior Shank Accuracy
Supports h4 tolerance (0/-0.004)
