2HRB 65 R0.75xD4x16x50 Long Neck Ball Nose Cutters

Description

2HRB 65 R0.75×D4×16×50 long neck ball nose cutter is a high-performance solid carbide CNC milling tool designed for precision machining in hardened materials up to 65 HRC. Featuring a 0.75 mm ball radius and long neck design, this cutter is ideal for deep cavity machining, 3D contouring, and detailed mould finishing in D2 steel, hardened P20, tool steel, stainless steel, and alloy steel.

Manufactured from premium micro-grain carbide rod and protected with a high-performance coating, this tool delivers excellent heat resistance, edge stability, and long tool life even in high-speed CNC operations. The 2-flute (2HRB) geometry ensures smooth chip evacuation, reduced cutting pressure, and vibration-free machining, which is critical for small-radius cutting and precision surface finishing.

With a 4 mm cutting diameter, 16 mm flute length, and 50 mm overall length, the long neck design allows easy access to deep mould cavities, narrow slots, and complex 3D features without tool interference. The D4 shank ensures strong tool holding and low run-out, resulting in high dimensional accuracy and superior surface quality.

This cutter is widely searched as 65 HRC ball nose end mill, long neck ball nose cutter, CNC mould milling tool, and precision carbide tools India, making it a preferred choice for CNC cutting tools manufacturers, industrial cutting tools suppliers, and CNC tools supplier in India who require high accuracy, reliability, and excellent surface finish in hardened steel machining.
