A ball end mill for high-precision finishing of high-hardness steel with emphasis on machined surface accuracy. By adopting the new “DUROREY” coating ideal for high-hardness steel, high chipping resistance is made possible even for work materials exceeding 60 HRC, enabling longer tool life.
4-flute high-efficiency carbide ball end mill for high-hardness steel (AE-BM-H).
Features
- Newly developed DUROREY coating enables superior heat resistance and high toughness optimized for high-hardness steel milling!
(1) Thickening of the center core to prevent deformation of the ball tip and improve control of chipping.
(2) Superior ball R precision ±0.005
- Superior shank accuracy. Supports h4 tolerance (0/-0.004).
- AE-BD-H: Variable negative spiral gash
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.
- AE-LNBD-H: Teardrop-shaped outer periphery
Strong back taper geometry enables milling by point, which prevents chattering and chipping, resulting in improvement of surface accuracy.
