2HRB 55 R0.5xD4x10x50 2f 55 hrc long neck ball nose

Description

2HRB 55 R0.5xD4x10x50 2f 55 hrc long neck ball nose end mill developed for CNC machining in materials up to 55 HRC. This tool is specially engineered for die & mould machining, enabling accurate milling of deep ribs, narrow cavities, fine contours, and intricate 3D profiles where tool reach and stability are critical. The R0.5 ball radius allows extremely fine detailing and smooth finishing on mould inserts, ribs, slots, and complex geometries.

Manufactured from premium micro-grain carbide rod, this cutter delivers excellent edge strength, wear resistance, and thermal stability, ensuring reliable performance during high-speed CNC milling. The 2-flute (2F) geometry is optimized for efficient chip evacuation and reduced cutting forces, minimizing vibration during long-reach operations and improving surface finish. This makes the tool highly suitable for machining P20 steel, stainless steel, EN8, EN19, alloy steel, and other medium-hard materials commonly used in mould and precision component manufacturing.

With a 10 mm flute length and 50 mm overall length, the long neck design provides safe clearance and easy access to deep pockets and thin ribs without tool interference. The D4 shank ensures strong clamping and low run-out, resulting in accurate profiles, consistent dimensional control, and reduced polishing time.

This tool is frequently searched as long neck ball nose cutter, rib cutter, 55 HRC carbide ball end mill, precision carbide tools India, die and mould machining tools, and high performance end mills. It matches buyer intent for CNC cutting tools manufacturers, industrial cutting tools suppliers, and CNC tools supplier in India seeking reliable solutions for precision milling and finishing.

The 2HRB 55 R0.5xD4x10x50 2F is widely used in plastic injection moulds, automotive mould components, precision engineering parts, and tooling inserts, where fine detail, smooth surface finish, and repeatable accuracy are essential. Its design supports stable deep machining, longer tool life, and consistent results, making it a dependable choice for modern CNC mould shops.
