4HRE 55 3.0xD4x30x75 4f long neck

Description

4HRE 55 3.0xD4x30x75 4F Long Neck 55 HRC End Mill is a precision solid carbide end mill designed for stable CNC machining of 55 HRC materials, including P20, SS304, SS316, alloy steel, and pre-hardened steels. The long neck design enables safe machining in deep cavities, narrow pockets, and complex profiles, reducing tool interference while maintaining rigidity and accuracy.

The 4-flute geometry delivers excellent cutting stability, reduced vibration, and improved surface finish during slotting, side milling, contouring, and finishing operations. With a 3.0 mm cutting diameter, 30 mm flute length, and 75 mm overall length, this cutter offers the ideal balance of reach and strength for die and mould applications that demand precision in confined areas.

Engineered for consistent performance, this 55 HRC carbide end mill provides reliable wear resistance, thermal stability, and long tool life in continuous CNC operations. It is widely used in die and mould machining, automotive tooling, aerospace components, and precision engineering, where dimensional accuracy and surface quality are critical.
