GEK 4R 4.0xD4x15(R0.5)X75

Description

GEK 4R 4.0xD4x15 (R0.5) X75 is a high-performance solid carbide corner radius end mill from the GEK series, specially engineered for precision CNC machining of D2 steel, SS316, cast iron, hardened tool steel, and 45–55 HRC materials. The GEK series is developed for demanding machining conditions where cutting stability, edge strength, and dimensional accuracy are critical.

The 4-flute (4R) geometry ensures excellent rigidity, reduced vibration, and improved surface finish during slotting, side milling, profiling, and finishing operations. The R0.5 corner radius provides a sharper cutting profile compared to larger radii while still strengthening the cutting edge and reducing chipping in hardened materials. With a 4.0 mm cutting diameter, 15 mm flute length, and 75 mm overall length, this cutter offers the right balance of reach and control for detailed die and mould features.

This GEK series carbide end mill is widely used in die and mould machining, automotive tooling, aerospace components, CNC tool rooms, and precision engineering applications. Optimized cutting-edge geometry supports smooth chip evacuation, controlled heat generation, and consistent tool life during continuous CNC machining.

Customers searching for carbide end mill for D2 steel, corner radius end mill R0.5, CNC cutting tools manufacturers, industrial cutting tools suppliers, precision carbide tools India, die and mould machining tools, or best carbide end mill for hardened steel will find this tool ideal for professional CNC environments. As a trusted industrial cutting tools supplier, we provide GEK-series carbide end mills designed for durability, precision, and cost-effective machining.
