6JJCRL (JJ 45º Helix Corner Radius)
- Endmills for pre-hardened and hardened steel (HRc52~70)
- Good wear resistance by high quality Si-based PVD coating.
- 45° degree helix design for high speed, feed condition.
- Excellent surface roughness for side, corner, shoulder milling and
- improved wear resistance due to increased edge length.
- Qutstanding performance at high speed machining by ultra fine (0.2um) WC grade.
