Ball end mills, or ball nose end mills, are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool.
Ball end mills, also known as "ball nose" end mills or full-radius end mills, have a constant single radius – or ball – at the end of the cutting tool. The nose radius is equal to half the …
