3 Flute, Square - Variable Pitch

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

HSV-3 | Carbide End Mills

The HSV-3 combines tool strength with superior performance. The eccentric relief of this 3 flute, variable pitch tool adds toughness and durability to the cutting edge, while its comparatively low flute count and Aplus coating allow for efficient chip evacuation.

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