2HRB R1.5xD4x30x75 2f rib 55 hrc long neck ball nose

Description

2HRB R1.5xD4x30x75 2f rib 55 hrc long neck ball nose cutter designed for precision CNC machining of ribs, deep cavities, and narrow profiles in materials up to 55 HRC. This tool is ideal for die & mould machining, where access to deep features with minimal tool interference and excellent surface finish are critical. The R1.5 ball radius combined with a slim D4 neck enables accurate machining of thin ribs, slots, and complex 3D contours in P20 steel, stainless steel, EN8, EN19, and alloy steels.

Manufactured from premium micro-grain carbide rod, the cutter delivers superior edge strength, wear resistance, and thermal stability, supporting high-speed CNC milling with consistent results. The 2-flute (2F) geometry is optimized for efficient chip evacuation and reduced cutting forces, minimizing vibration and improving tool life during deep rib machining and finishing passes. This geometry is especially effective for long-reach applications, where stability and surface quality are essential.

With a 30 mm flute length and 75 mm overall length, the long neck design provides the reach needed for deep mould cavities and tall walls, while maintaining rigidity for controlled cutting. The balanced design ensures low run-out, accurate profiles, and smooth surface finish, reducing rework and polishing time on mould components.

This tool is commonly searched as long neck ball nose cutter, rib cutter, 55 HRC carbide ball end mill, CNC mould milling tool, precision carbide tools India, and aligns with buyer intent for high performance end mills used by industrial cutting tools suppliers and CNC cutting tools manufacturers. It is widely applied in mould inserts, ribs in plastic injection moulds, automotive components, and precision engineering parts where repeatability and finish matter.

By enabling stable deep machining with clean geometry, the 2HRB R1.5xD4x30x75 2F helps improve productivity, extend tool life, and deliver consistent quality in demanding CNC environments.
