GEK 4R 4.0xD4x16(R1.0)X100

Description

GEK 4R 4.0xD4x16 (R1.0) x100 is a high-performance solid carbide corner radius end mill from the GEK series, engineered for precision CNC machining of D2 steel, SS316, cast iron, hardened tool steel, and 45–55 HRC materials. The GEK series is specifically developed for demanding machining conditions where wear resistance, edge strength, and dimensional accuracy are critical.

The 4-flute (4R) geometry ensures high 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 when machining hardened materials. With a 4.0 mm cutting diameter, 16 mm flute length, and long 100 mm overall length, this cutter is ideal for deep cavity machining, mould cores, and precision contouring where extra reach is required.

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 ensures smooth chip evacuation, stable cutting action, and consistent performance in continuous CNC machining.

Customers searching for carbide end mill for D2 steel, corner radius end mill 55 HRC, 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 perfectly suited for professional CNC environments. As a trusted industrial cutting tools supplier, we deliver GEK-series carbide tools engineered for durability, precision, and cost-effective machining.
