4-flute high-precision finishing carbide ball end mill for high-hardness steels
Features & Benefits
Superior Ball R Precision
Secures stable R accuracy across 180°
Superior Shank Accuracy
Supports h4 tolerance (0/-0.004)
Thickness at Center
Thickening of the center core to prevent deformation of the ball tip and improve control of chipping
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
