4 Flute Carbide Ball Double 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
AlTiN (Aluminum Titanium Nitride) coating is ideal for high temperature cutting operation in many materials such as titanium and nickel alloys, Co-Cr-Mo, stainless steel, alloy steels and cast iron. When exposed to higher temperatures, it forms a hard aluminum oxide layer and, as temperatures increase, the coating insulates the tool and transfers heat into the chips. It is an extremely tough coating that will hold up in heavy and interrupted cuts. AlTiN contains a higher aluminum content than the similar TiAlN coating which makes it much harder and smoother than TiAlN. AlTiN is ideal for smaller depths of cut and excels in high speed and dry machining applications and when machining hardened steel.
