4HRE 65 3.0xD6x20x50-long neck End Mill
4HRE 65 3.0xD6x20x50-long neck End Mill is designed for high-precision machining of hardened steels like D2, H13, and other materials ranging from 48 to 55 HRC. Engineered from premium solid carbide and coated with advanced AlTiN or TiSiN, it delivers excellent wear resistance, heat stability, and extended tool life. The long neck design allows deep cavity milling, fine contouring, and high-performance cutting in hard-to-reach areas—perfect for die & mould making, aerospace components, and automotive parts.
Available in micro diameters (starting from 0.2 mm) up to 20 mm, with options for corner radius and extended length, this tool ensures clean finishes and tight tolerances even under high-speed CNC conditions. If you’re working with hardened steels, this end mill is your go-to tool for superior surface finish and durability.
