HEV-7 | Carbide End Mills

The HEV-7 is designed to withstand and excel in the toughest applications and materials. The high flute count and variable pitch geometry give this tool the strong core and extreme performance necessary for steels, high temperature alloys, and titanium.

  • Variable pitch geometry results in higher quality parts by decreasing chatter and harmonics
  • End cutting geometry (non-center cutting) 
  • Excellent performance in High Efficiency Milling (HEM)
  • 7 flute design offers a large core for added strength
  • h6 shank tolerance for high precision tool holders
  • Aplus coated for added lubricity, higher speeds and feeds, and increased wear resistance
  • Tplus coated for optimal tool life in rigid machining setups

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.
