Basic End Mills Technical Information | MSC Industrial ...

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.

The nose radius should be kept around 1/64″ for steel and 1/32″ or so for non ferrous metals. If it's too small, it will burn out quickly on steel, too large and it will chatter. Fly cutters dissipate heat better than end mills, so I generally run them 30%-50% faster than an end mill of equal size.
