2 Flute Carbide Ball Double End mills provide enhanced chip carrying capability and are ideal for slotting and pocketing applications.provide maximum chip removal and are used to produce shallow holes. 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.
