Profile Milling Insert is a common milling operation. Round inserts and concepts with radius are milling cutters used for roughing and semi-roughing while ball nose end mills are milling cutters used for finishing and super-finishing. High Feed Milling Insert is a milling method that permits up to three times faster machining than conventional methods. It pairs shallow depth of cut with high feed per tooth which gives higher metal removal rates and results in more parts being machined. http://www.wecotools.com/milling-inserts/profile-milling-insert/
