Sandvik Coromant (coromant.sandvik.com) has developed a new family of CoroMill Plura ball nose end mills for profiling in medium hard to hard steels (35-72 HRc). They’re available in diameters ranging from 0.1 to 12 mm and intended for high-precision die and mold applications. The end mills feature long necks for accessibility in pocket milling. They also feature a geometric design that prevents radius deterioration from uneven wear. They’re produced in a fine-grained solid carbide grade with multi-layered PVD coating.
