The 5 flute design of the HEV-RN-5 provides a significant lift in tool life and productivity, while increasing feed rate 20 percent over a 4-fluted tool. Its variable pitch geometry and strong core work in tandem with the reduced neck to make this tool capable of excelling in long reach applications in tough materials.

  • Excellent performance in light profiling, High Efficiency Milling (HEM), and finishing applications
  • 5 flute variable pitch design for reduced harmonics and increased feed rates
  • Reduced neck provides maximum strength in long reach and deep pocketing applications
  • Center cutting
  • h6 shank tolerance for high precision tool holders
  • Aplus coated for added lubricity, higher speeds and feeds, and increased wear resistance
