NTK Cutting Tools

The CERAMATIC series of productive ceramic end mills enables rough milling of nickel‑based alloys at speeds up to 10 times faster than conventional carbide tools.

Extremely high-speed machining for heat-resistant superalloys (HRSA).
Features
  • Increase productivity 10 times, comparing with carbide tools Vc up to 600m/min 2,000SFM
  • Unique bottom‑edge geometry helps prevent sudden tool breakage
4 flute type

Designed with a focus on toughness

6 flute type

Reduces cutting forces while improving chip evacuation

  • A continuous cut is recommended. An interrupted cut may cause chipping or breakage.
  • Continue to machine even if you see burr, removing burr may cause chipping or breakage to the edge.
  • A Minimum speed of 300m/min 980SFM is required. (Don’t run at lower speed)
  • 0.5 degree ramping angle is recommended. Run at 50% lower feed rate when ramping cut.
