7 Flute, Square - Variable Pitch

End Mills for Steels, High-Temp Alloys, & Titanium

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) allows for ramping
  • 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
