H45AL-RN-3 Square

The H45AL-RN-3’s reduced neck, combined with its high helix design, provides maximum strength in long reach applications where finish is a priority, and the Zplus coating provides additional tool life and increased chip evacuation.

  • High helix for increased part finish and shearing action
  • Cylindrically ground to maintain edge strength
  • Reduced neck provides maximum strength in long reach and deep pocketing applications
  • Excellent performance in High Efficiency Milling (HEM)
  • Center cutting
  • h6 shank tolerance for high precision tool holders
