Product Description
[Features]
· ball end mill for high-precision finishing that
focuses on machined surface precision, and a new coating "DUROREY" coating for
high-hardness steel that is excellent even for work materials over 60 HRC.
Demonstrates chipping resistance and enables longer tool life.
2-flute high-precision finishing Carbide ball end mill for high hardness steel
AE-BD-H
1 Variable negative spiral gash
• Controls chipping with larger negative angle at tip of cutting edge.
• 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.
2 Thickness at the center
• Thickening of the center core to prevent deformation of the ball tip and improve control of chipping.
3 Superior ball R precision
• Secures stable R accuracy across 180°.
4 Superior shank accuracy
• Supports h4 tolerance (0/-0.004).
5 Ideal for shrink fit holders
• Lineup of short-shank type suitable for shrink fit holders are also available.
6 Smooth Surface Treatment
• Improves surface accuracy by smoothening the coating surface.
Long Tool Life
Exhibitts superior endurance in high-hardness steel milling
High-speed Milling
Enables stable machining even in high-speed milling of STAVAX (53 HRC)

1. Use a rigid and precise machine and holder.
2. Using air blow or MQL (oil mist coolant) is recommended.
3. The above condition shows an approximate standard for contouring operation (side milling) with a low machining load. If abnormal cutting sounds, vibration
or chattering occur depending on the machining shape, cutting amount, rigidity of the machine or work holding condition, etc., please adjust the speed,
feed and the depth of cut.
4. Cutting speed and feed rate can be increased in case of lower depth of cut.
