3/8" High Performance Carbide End Mill 6 Flute Extra Long Length 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 3/8" diameter and an overall length of 4 inches (extra long length). It has a single end and is center cutting. This cutter has 6 flutes, which is best used for many applications including high temperature alloys, stainless steels, alloy steels, cast iron, high temperature nickel based alloys, and titanium alloys. It also 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.
