What is a Ball End Mill?

Protective coatings have been in use since the early 1990s, and many advances have been made since then. In the mid- 2000s, amorphous diamond coatings were beginning to be seen on some higher-end mills. Even with the toughest coating, though, a ball end mill .

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.
