5/16" High Performance Carbide End Mill 5 Flute 45° Helix ALTiN
All Atlas solid carbide end mills are manufactured in the USA with only the highest grade carbide available. This high performance end mill has a square end cut with a 5/16" diameter and an overall length of 2-1/2 inches (regular length). It has a single end and is center cutting. This cutter has 5 flutes, which works well in all exotic materials, including stainless steels and carbon steels and has a 45° helix that allows the tool to be run 20-40% faster than conventional endmills while producing an excellent finish. This end mill is ALTiN coated. ALTiN coating is a high performace coating with extremely high thermal stability (750 Degree's C/1350 Degree's F) that is used for milling, tapping and drilling in stainless steels, carbone steels, alloy steels, and cast iron. This coating can be used with or without coolant. It performs exceptionally well in difficult to machine materials and will dramatically increase overall tool life.
