GEK 4R 5.0xD5x20(R0.5)X75 4f (65)

Description

GEK 4R 5.0xD5x20 (R0.5) x75 4F (65 HRC) is a premium solid carbide corner radius end mill from the GEK series, specially developed for high-precision CNC machining of 65 HRC hardened materials such as D2 steel, hardened tool steel, SS316, cast iron, and high-hard P20. This series is engineered for extreme machining conditions where wear resistance, cutting stability, and dimensional accuracy are critical.

The 4-flute (4F) geometry provides excellent rigidity, controlled cutting forces, and reduced vibration, enabling smooth slotting, side milling, profiling, and finishing operations. The R0.5 corner radius offers a sharp yet reinforced cutting edge, allowing fine detailing while significantly reducing edge chipping compared to sharp-corner tools. With a 5.0 mm cutting diameter, 20 mm flute length, and 75 mm overall length, this cutter is ideal for deep cavity machining, mould cores, and precision contouring where extended reach and stability are required.

This 65 HRC carbide end mill is widely used in die and mould machining, aerospace components, automotive tooling, CNC tool rooms, and precision engineering industries. Optimized cutting-edge geometry ensures stable machining, controlled heat generation, excellent surface finish, and consistent tool life in continuous CNC operations.

Customers searching for 65 HRC carbide end mill, corner radius end mill R0.5, carbide end mill for D2 steel, CNC cutting tools manufacturers, industrial cutting tools suppliers, precision carbide tools India, or die and mould machining tools will find this GEK-series cutter ideal for demanding professional CNC applications. As a trusted industrial cutting tools supplier, we deliver GEK-series carbide end mills engineered for durability, precision, and cost-effective hardened steel machining.
