Ball End Mills (Ball Nose) Carbide Cobalt & HSS

Ball End Mills. A ball end milling cutter is also known as a "ball nose mill". The end of this tool is ground with a full radius equal to half of the tool diameter, and the edges are center cutting. They can be single end or double end and they can be made from solid carbide or various compositions of high speed steel.
