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

Below are downloadable Simulation Files in DXF format (half-round line drawings) to accompany Harvey Tool products. Each file is specifically scaled to the geometry of the tool to help simulate running parameters and create tool paths. Like our speeds & feeds charts, these files will be continuously updated with the introduction of new products and new catalogs to assist operating the majority of our tools. Simulation files can also be accessed by searching for a specific tool number on the left-hand side of the website and then clicking on the Simulation table in the product table.
