GEK 4R 8.0xD8x3X1005(R0.5)

Description

GEK 4R 8.0×D8×35 (R0.5) × 100 corner radius end mill is a high-performance solid carbide CNC milling cutter designed for precision machining of hardened steel, alloy steel, and mould materials. With a 4-flute geometry and R0.5 corner radius, this tool provides excellent edge strength, vibration control, and smooth surface finish, making it ideal for die & mould machining, aerospace components, and precision engineering applications.

Manufactured from premium micro-grain carbide rod and coated with a wear-resistant layer, this cutter delivers high heat resistance, wear stability, and long tool life when machining D2 steel, P20 steel, stainless steel, and 48–65 HRC materials. The 4-flute design allows stable cutting, higher feed rates, and improved surface quality in high-speed CNC machining.

With an 8 mm cutting diameter, 35 mm flute length, and 100 mm overall length, this end mill offers the ideal balance of reach and rigidity for deep cavity machining, contour milling, pocketing, and finishing operations. The D8 shank ensures strong tool holding and low run-out, improving dimensional accuracy and surface finish.

This cutter is widely searched as 8 mm carbide end mill, corner radius end mill, CNC milling tool for D2 steel, and precision carbide tools India. It is commonly used by CNC cutting tools manufacturers, industrial cutting tools suppliers, and CNC tools supplier in India for producing high-accuracy moulds and precision components.
