HX55 10mm Long Series 4 Flute Square Carbide End Mill

The Helixor HX-55 10mm Long Series 4-flute square solid carbide endmill is engineered for deep-reach machining in hardened steels. Made from sub-micron tungsten carbide and hardened to 55 HRC, it maintains stability and edge strength at extended lengths. The TiSiN coating enhances thermal resistance and durability, while eccentric relief and variable pitch geometry reduce vibration for controlled, high-precision cutting.
