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.

  • High helix for increased 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 for maximum performance in aluminum and non-ferrous alloys

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.
