HSV-4 | Carbide End Mills

The HSV-4’s variable pitch geometry effectively decreases chatter and harmonics, allowing it to leave a better part finish and last longer in your spindle. Featuring eccentric relief for maximum edge strength and Aplus coating for improved performance in tough materials, this tool is a strong choice for a variety of applications.

  • Eccentric relief for maximum edge strength
  • Special geometry allows for both roughing and finishing applications
  • Variable pitch geometry results in higher quality parts by decreasing chatter and harmonics
  • Center cutting
  • h6 shank tolerance for high precision tool holders
  • Aplus coated for added lubricity, higher speeds and feeds, and increased wear resistance
