HPC 4 Flutes Ball Nose Endmill
Our HPC 4-flute ball nose end mills are engineered to maximise productivity in demanding machining applications. Thanks to their optimised geometry and differential cutting-edge design, this range delivers excellent surface finish, high wear resistance and consistent machining precision, ensuring extended tool life even in the most demanding cutting cycles.
To further enhance performance, all tools are supplied as standard with our exclusive latest-generation Cer-Y coating. This advanced coating forms a protective barrier that significantly reduces friction and prevents chip build-up, enabling dry or minimum-lubrication machining while ensuring outstanding cutting-edge durability, even when machining the most challenging materials.
Shank Options:
• HA - Standard cylindrical (640.)
• HB - Weldon (640W.)
