4 Flute HRC55 Long Reach Reduced Shank Carbide End Mill TiSiN Coated for Steel Milling

The HRC55 Solid Carbide 4 Flute Flat End Mill is designed for high-efficiency machining of hardened steel, offering excellent performance in roughing and semi-finishing applications. Manufactured from premium solid carbide with advanced coating, it ensures high rigidity, wear resistance, and stable cutting performance under demanding CNC conditions.

The 4-flute geometry provides enhanced tool stability and improved surface finish compared to lower flute count tools, making it suitable for steel and mold steel machining where precision and consistency are required.

The reduced shank design (6mm) allows better tool clearance in deep cavity machining, reducing interference and improving machining flexibility. This structure makes it especially suitable for complex mold cavities and narrow working spaces.

The step roughing capability enables efficient material removal while maintaining tool stability, reducing machining time and improving productivity in industrial CNC applications.
