2HRB65 R2.0xD4x12x50 2f (65)

Description

2HRB65 R2.0xD4x12x50 is a high-performance solid carbide long neck ball nose end mill engineered for precision CNC machining in hardened materials up to 65 HRC. This cutter is specially designed for die & mould machining, where deep cavity access, rib machining, and complex 3D profiling demand high rigidity, excellent surface finish, and long tool life. The R2.0 ball radius combined with a slim D4 neck allows accurate machining of narrow areas, deep ribs, and fine contours without tool interference.

Manufactured from premium micro-grain carbide rod and coated for high hardness applications, this tool offers superior wear resistance, edge stability, and thermal strength, even under high-speed CNC milling conditions. The 2-flute (2HRB) geometry is optimized for hardened steel machining, ensuring smooth chip evacuation, low cutting pressure, and reduced vibration, which are critical when working on D2 steel, hardened P20, tool steel, SS316, and other 55–65 HRC materials.

With a 12 mm flute length and 50 mm overall length, the long neck design provides the required reach for deep mould cavities and tall walls, while maintaining stability for finishing operations. The tool delivers excellent surface finish, reducing manual polishing time on mould components and improving overall productivity.

This cutter is widely searched online as 65 HRC ball nose end mill, long neck ball nose cutter, carbide rib cutter, precision carbide tools India, high performance end mills, and die and mould machining tools. It aligns perfectly with buyer intent for CNC cutting tools manufacturers, industrial cutting tools suppliers, and CNC tools supplier in India who require reliable solutions for hardened steel machining.

The 2HRB65 R2.0xD4x12x50 is commonly used in plastic injection moulds, die inserts, automotive mould components, aerospace tooling, and precision engineering parts, where accuracy, consistency, and tool life are critical. Its design supports stable deep machining, accurate geometry, and repeatable results, making it an essential tool for modern CNC mould shops.
