HRC65 Mold Steel End Mill【4 Flutes Long Neck Φ 1-3】

Designed for Hardened Steels up to 65HRC – Ideal for Deep Feature Machining
Engineered for precision machining of hardened tool steels (up to 65HRC), the tool combines a high-strength carbide substrate with an extended neck design, making it ideal for deep cavity milling, narrow features, and areas requiring extra reach without sacrificing stability.

4-Flute Geometry for High Material Removal and Surface Finish Optimization
The 4-flute configuration increases cutting edge contact, allowing for faster feed rates and smoother finishes compared to 2-flute tools. It’s especially effective in semi-finishing and finishing of hardened molds, reducing passes and cycle time.

Long Neck Design Balances Reach and Rigidity – Perfect for Mold Cores and Deep Contours
With a shortened flute length and reinforced neck, this tool provides sufficient stiffness for deep-pocket machining, minimizing tool deflection and vibration. It’s particularly suited for precision mold cavities, ribs, slots, and intricate 3D surfaces.

High-Red-Hardness Coating for Heat Resistance in Dry or MQL Machining
Featuring a premium nano-layer coating (e.g., TiAlN or similar), the tool withstands extreme thermal loads during high-speed dry or minimal-lubrication machining. It ensures extended tool life and consistent cutting performance under demanding conditions.

Complete Cutting Data Provided for Consistent and Efficient Results
Each tool includes application-tested cutting parameters tailored for high-HRC materials—such as speed, feed, and depth of cut—helping CNC programmers and operators reduce setup time, avoid trial-and-error, and maximize productivity from day one.
