GEK 4R 10.0xD10x25(R1.0)X75

Description

GEK 4R 10.0×D10×25 (R1.0)×75 corner radius flat end mill is a high-performance 65 HRC solid carbide milling cutter engineered for precision machining of hardened steel, tool steel, and mould materials. Designed with a 1.0 mm corner radius, this cutter eliminates sharp edges, improves tool strength, and reduces chipping, making it ideal for die & mould machining, aerospace components, automotive parts, and high-accuracy CNC milling applications.

Manufactured from premium micro-grain carbide rod and coated with advanced wear-resistant PVD coating, this end mill provides excellent heat resistance, edge stability, and long tool life when machining D2 steel, hardened P20, SS316, tool steel, and 48–65 HRC materials. The 4-flute (4R) geometry ensures stable cutting, smooth chip evacuation, and superior surface finish even under high-speed and heavy-load machining conditions.

With a 10 mm cutting diameter, 25 mm flute length, and 75 mm overall length, this tool offers an optimal balance between reach and rigidity, making it suitable for slotting, pocketing, side milling, and finishing operations in hardened materials. The D10 shank provides strong clamping and minimal run-out, improving accuracy and reducing vibration during high-speed CNC machining.

This cutter is widely used by CNC cutting tools manufacturers, industrial cutting tools suppliers, and precision carbide tools India markets for machining mould cavities, die inserts, aerospace brackets, and precision mechanical parts. It is commonly searched under carbide end mill tools, high performance end mills, 65 HRC carbide tools, carbide tools for 48–55 HRC materials, and best carbide end mill for D2 steel.

The corner radius design (R1.0) improves tool strength and allows smoother blending of surfaces, reducing tool wear and improving component quality. This makes the GEK 4R series ideal for finishing and semi-finishing operations in hardened steel machining.
