Hepyc HSSE End Mill DIN 327N

The Hepyc HSSE End Mill is a short-series cobalt high speed steel (HSSE) milling cutter manufactured to DIN 327N, designed for stable finishing and light profiling work. Featuring a 30° helix and 2 cutting teeth (2 flutes), it delivers smooth chip evacuation and reliable surface finish in common steels and selected non-ferrous materials.

Built for consistent performance, this cutter’s straight cut geometry and compact short-series design help reduce chatter and improve control, making it ideal for precise finishing passes and general workshop milling.

Recommended Cutting Speed (Vc)

The cutting speed values below are indicative starting points and should be adjusted according to machine rigidity, tool diameter, coolant use, and cutting conditions.

• P – Steels
  • >800 N/mm²: 30–50 m/min
  • >1,000 N/mm²: 25–30 m/min
• M – Stainless steels
  • >950 N/mm²: 15–20 m/min
• K – Cast irons
  • >500 N/mm²: 34–38 m/min
  • >800 N/mm²: 20–24 m/min
• N – Non-ferrous metals
  • Cu alloys: 45–90 m/min

Notes

• Short-series design improves rigidity and surface finish.
• Use coolant where possible to maximise tool life in steel applications.
