4HRE 65 2.0xD4x20x50-long neck End Mill

Description

4HRE 65 2.0xD4x20x50-long neck End Mill-Unlock high-precision machining with our 65 HRC Long Neck Carbide End Mill, expertly engineered for deep cavity milling, hard material processing, and fine surface finishing. Manufactured from ultra-micro grain carbide (0.6μm) and coated with advanced Blue Nano Coating, this tool delivers exceptional hardness, wear resistance, and heat stability.
The long neck design ensures superior reach and rigidity, minimizing tool deflection during high-speed operations. It’s especially suited for machining hardened steel up to 65 HRC, including alloy steel, tool steel, and die steel, making it an ideal choice for mold & die industries, aerospace components, and precision engineering.
Whether you’re performing slotting, profiling, or contour milling, this long neck cutter offers consistent performance and long tool life — saving time, cost, and reducing tool changes.
With a helix angle of 35°, a robust 4-flute design, and optimized flute geometry, this end mill ensures smooth chip evacuation and a mirror-like surface finish, even under demanding conditions.
