HRC65 Ball Nose End Mill 【2 Flutes Long Neck R0.1-R2】

Specialized for Deep Cavity and Fine Feature Machining in Hardened Steel (≤65HRC)
Designed to machine hardened tool steels up to 65HRC, this tool combines a high-strength micro-grain carbide substrate with a precision long neck structure—ideal for deep mold cavities, narrow ribs, and detailed 3D surfaces where tool reach and stability are critical.

2-Flute Design Enhances Chip Flow and Cutting Control in Hard Materials
The open flute design ensures efficient chip evacuation, reduces cutting forces, and minimizes vibration during deep or intricate contouring. Especially suited for semi-finishing and finishing in hard-to-reach areas.

Precision Ball Nose Geometry for Complex 3D Surface Profiling
The spherical tip delivers excellent contouring performance and smooth surface finishes. Perfect for high-precision applications such as electrode machining, medical component milling, and 3D mold surface finishing where surface integrity is paramount.

Long Neck, Short Flute Ratio Ensures Rigidity and Reach in One Tool
Engineered with a carefully calculated neck-to-flute length ratio, the tool minimizes deflection while allowing deep access into complex geometries. This reduces the need for multiple tool changes and boosts machining accuracy in tight spaces.

Advanced Thermal-Resistant Coating for High-Speed, Low-Lubrication Operations
Featuring a high red hardness nano-coating (e.g., HG), the tool maintains sharpness and wear resistance at elevated temperatures, supporting dry and MQL machining strategies—meeting modern demands for high-efficiency and eco-friendly production.

Cutting Parameters Provided – Faster Setup, Stable Performance
Every tool comes with verified cutting data tailored for hardened steels, helping users maximize tool life, reduce trial-and-error during setup, and achieve consistent results even in complex 3D finishing applications.
