2HRB 65 R1.0xD4x30x75-Long neck Ball Nose

Description

2HRB 65 R1.0xD4x30x75-Long neck Ball Nose Cutter is a high-precision solid carbide cutting tool designed for machining hardened materials with exceptional accuracy and surface finish. With a 1.0 mm ball radius, 4 mm shank, 30 mm flute length, and 75 mm overall length, this long-neck cutter is ideal for deep cavity machining, 3D contouring, and die & mould finishing where tool reach and rigidity are critical.

Engineered for 65 HRC hardness, this cutter performs reliably in D2 steel, hardened tool steel, high-hard P20, SS316, and other tough alloys. The advanced carbide grade and wear-resistant coating provide excellent heat resistance, reduced friction, and long tool life, even in high-speed CNC machining. The 2-flute geometry ensures smooth chip evacuation and stable cutting in hard materials, producing superior surface quality and consistent dimensional accuracy.

The long-neck design minimizes tool interference in deep pockets and complex shapes, making this tool perfect for aerospace components, die and mould machining, automotive parts, medical tooling, and precision engineering applications. It allows efficient machining of fine details, fillets, and curved surfaces without compromising strength or stability.

Suitable for use on VMCs, high-speed CNC milling machines, and 5-axis machining centers, the 2HRB R1.0 × D4 × 30 × 75 (65 HRC) long neck ball nose end mill delivers excellent performance, reduced vibration, and extended tool life, helping manufacturers achieve higher productivity and superior finishing in hardened material machining.
