2HRB 55 R0.75xD4x08x50 2f 55hrc long neck ball nose

Description

2HRB 55 R0.75xD4x08x50 2F 55 HRC Long Neck Ball Nose is a precision solid carbide long neck ball nose end mill designed for CNC machining of hardened and pre-hardened materials up to 55 HRC. With an R0.75 ball radius, 4 mm cutting diameter, 8 mm long neck, and 50 mm overall length, this tool is ideal for deep cavity machining, 3D contouring, profiling, and finishing operations where reach and accuracy are critical.

Manufactured from high-quality micro-grain carbide, this long neck ball nose cutter offers excellent wear resistance, edge toughness, and thermal stability. The 2-flute (2F) geometry ensures smooth chip evacuation, reduced cutting forces, and stable cutting performance, especially important in long-reach applications where vibration control is essential. The long neck design provides proper clearance while machining deep pockets, ribs, and complex mould features without tool interference.

This cutter performs reliably on P20 steel, EN8, EN19, alloy steel, and stainless steel within the 55 HRC range. It is widely used in die & mould machining, automotive components, precision engineering, and general CNC milling applications requiring fine surface finish and dimensional accuracy.
