GEK 4R 3.0xD3x8(R0.5)X50

Description

GEK 4R 3.0xD3x8 (R0.5) x50 is a high-performance solid carbide corner radius end mill from the GEK series, engineered for precision CNC machining of SS316, D2 steel, cast iron, and 45–55 HRC materials. The GEK series is designed for tougher cutting conditions where edge strength, wear resistance, and dimensional stability are essential.

The 4-flute (4R) geometry delivers excellent rigidity, reduced vibration, and superior surface finish during slotting, side milling, profiling, and finishing operations. Featuring a R0.5 corner radius, this tool significantly improves edge durability, reduces chipping, and extends tool life compared to sharp-corner end mills—especially beneficial in hardened steels and continuous machining cycles. With a 3.0 mm cutting diameter, 8 mm flute length, and 50 mm overall length, it offers precise control for compact features and mould details.

This GEK series corner radius end mill is widely used in die and mould machining, automotive tooling, precision engineering, and CNC tool rooms where accuracy and repeatability are critical. Optimized cutting edges ensure smooth chip evacuation, stable cutting action, and consistent performance under demanding conditions.

Customers searching for carbide end mill for D2 steel, 4 flute corner radius end mill, 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 cutter ideal for professional CNC environments. As a trusted industrial cutting tools supplier, we provide GEK-series carbide end mills engineered for durability, precision, and cost-effective machining.
