MILLING/SOLID - MILLING/BALL NOSE/8410

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
