• RedLine 3 Flute, Standard and Neck Relief Extra High Performance End Mills are designed for Roughing,
Finishing or Slotting in Aluminum and Non-Ferrous materials.
• The ZrN coated tools allow for higher speeds, better tool life with a low affinity for Aluminum.
• Use for straight line and helical ramping.
• These Extra High Performance tools can be found on pages 18-22, 24-25.
