2HRB 65 R0.75xD4x20x50 Long Neck Ball Nose Cutters

Description

Long Neck Ball Nose Cutters, engineered for extreme hardness applications. Made from ultra-fine grain solid carbide, these tools are specially designed for high-precision machining of hardened steel, mold steel, and die steel up to 48-55 HRC. The long neck geometry provides extended reach, allowing safe and stable deep cavity milling without vibration. Perfect for mold making, 3D contouring, rib machining, and intricate surface profiling, especially in difficult-to-machine materials.

With optimized ball nose geometry and a mirror-polished finish, these cutters deliver smoother surface quality, better chip evacuation, and minimal tool wear at high feed rates. Advanced coatings ensure excellent heat resistance and a longer tool life during dry or semi-dry machining.

Ideal for high-speed spindles, CNC machining centers, and finishing operations requiring fine tolerances, these ball nose cutters offer reliability and performance where precision matters most. Whether you’re working on hardened molds or complex aerospace parts, our 48-55 HRC long neck cutters provide the durability and accuracy required to meet industry demands. Experience unmatched control, stability, and finish with every cut.
