Basic End Mills Technical Information

Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.
