GEK 4R 4.0xD4x10(R1.0)X50

Description

GEK 4R 4.0xD4x10 (R1.0) x50 is a high-performance solid carbide corner radius end mill from the GEK series, specially designed for CNC machining of D2 steel, SS316, cast iron, hardened tool steel, and 45–55 HRC materials. The GEK series is developed for tougher machining conditions where edge strength, wear resistance, and dimensional stability are essential.

The 4-flute (4R) 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, reduces chipping, and significantly improves tool life compared to sharp-corner end mills, especially in hardened steel applications. With a 4.0 mm cutting diameter, 10 mm flute length, and 50 mm overall length, this cutter is ideal for compact mould features and precision contours.

This GEK series carbide end mill is widely used in die and mould machining, automotive tooling, aerospace components, CNC tool rooms, and precision engineering, where accuracy and repeatability are critical. Optimized cutting-edge geometry ensures smooth chip evacuation, stable cutting action, and reliable performance in continuous CNC operations.

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 highly suitable 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.
