4&6JJDRC (JJ Double Corner Radius)
- Endmills for pre-hardened and hardened steel
- Good wear resistance by high quality Si-based PVD coating.
- Designed for low speed with high feed condition.
- Suitable for heavy duty and roughing application.
- Minimize fracturing at high feed by high TRS ultra fine WC grade.
- Applied multi-radius design on the end face of the tool, reduced cutting stress by splitting small chip emission.
