4 flute carbide ball end mills excel in peripheral milling and finishing. 4 flute end mills provide a much finer finish and can be ran at faster rates. The hemispherical tip produces rounded details, where sharp corners must be avoided, and they are commonly used in dies and molds. Carbide’s extreme hardness allows for the tool to be run much faster than hss or cobalt. It provides a high degree of wear resistance by withstand high cutting temperatures. The rigidity of carbide allows for excellent surface finishes and dimensional accuracy
