GEK 4R 5.0xD5x20(R1.0)X75 4f (65HRC)

Description

GEK 4R 5.0xD5x20 (R1.0) x75 4F (65 HRC) is a high-performance solid carbide corner radius end mill from the GEK series, specially engineered for CNC machining of 65 HRC hardened materials, including D2 steel, SS316, cast iron, hardened tool steel, and high-hard P20. The GEK series is designed for demanding machining conditions where wear resistance, edge strength, and dimensional accuracy are critical.

The 4-flute geometry provides excellent rigidity, reduced vibration, and superior surface finish during slotting, side milling, profiling, and finishing operations. The R1.0 corner radius strengthens the cutting edge, minimizes chipping, and significantly extends tool life compared to sharp-corner end mills—especially beneficial in hardened steel machining. With a 5.0 mm cutting diameter, 20 mm flute length, and 75 mm overall length, this cutter offers an ideal balance of reach and stability for die and mould applications.

This 65 HRC carbide end mill is widely used in die and mould machining, aerospace components, automotive tooling, and precision engineering, where consistent accuracy and long tool life are essential. Optimized cutting edge geometry ensures stable cutting, controlled heat generation, and reliable performance during continuous CNC operations.

Customers searching for 65 HRC carbide end mill, corner radius end mill for D2 steel, 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 GEK-series cutter ideal for professional CNC environments. As a trusted industrial cutting tools supplier, we deliver GEK-series carbide tools engineered for durability, precision, and cost-effective hardened steel machining.
