Description The Helixor HX-55 12mm 4-flute square solid carbide endmill is designed for high-performance machining of hardened steels and ferrous materials. Manufactured from sub-micron tungsten carbide and hardened to 55 HRC, it delivers excellent rigidity, edge strength, and cutting stability. The TiSiN coating improves heat resistance, reduces wear, and extends tool life, while eccentric relief and variable pitch geometry minimize chatter and produce clean, accurate finishes in demanding applications.
