3 Flute, Square - 45° Helix

End Mills for Aluminum Alloys & Non-Ferrous Materials
3 Flute, Square - 45° Helix

H45AL-3 | Carbide End Mills

This tool’s 45° high helix makes it ideal for finishing due to its high shear angle and cutting aggressiveness. In addition, the high helix and 3 flute design simultaneously create efficient chip evacuation and metal removal rates.

  • Designed for outstanding performance and accelerated metal removal rates in aluminum and non-ferrous materials
  • Designed with a high helix for improved part finish and shearing action
  • Cylindrically ground to maintain edge strength
  • Center cutting
  • Excellent performance in High Efficiency Milling (HEM)
  • h6 shank tolerance for high precision tool holders
  • Zplus coating offers higher hardness and added lubricity for maximum performance
  • Solid carbide end mills
  • CNC ground in the USA
