3 Flute, Corner Radius - 45° Helix, Rougher, Chipbreaker

End Mills for Aluminum & Non-Ferrous Materials

H45AL-C-3 | Carbide End Mills

The unique tool design of our 3-flute, 45° helix chip breaker for aluminum means it requires less torque and horsepower to work its way through your part. As a result, your tool experiences reduced strain, increasing its durability and life while the chip breaker geometry enhances chip evacuation.

  • Offset chip breaker geometry creates smaller chips for optimal evacuation and a semi-finished surface
  • Unique tool design requires less torque and horsepower
  • 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
  • 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.
