Our precision Step Tungsten Carbide End Mill with 4 flutes is specifically engineered for aerospace component manufacturing. This high-performance forming cutter features an advanced step design that enables simultaneous roughing and finishing operations in titanium alloys (Ti-6Al-4V), Inconel, and aerospace-grade aluminum.

Manufactured from ultra-fine grain tungsten carbide with micro-grain structure, this tool delivers exceptional accuracy (±0.005mm) and surface finishes (Ra 0.2-0.4μm) critical for flight components.
