Bull Nose End Mill or Corner Radius End Mill

Bull end mills are simply corner radius end mill cutters.  These radius end mills are single ended tools used for making corner radii at the bottom of a milled shoulder. Bull nose cutters have a stronger milling edge than square end mills, so feed rates may be increased and yield longer tool life and greater productivity.  These milling bits may also be used in mold profiling applications leaving smoooth finishes.  These mills are all solid carbide, and are available in many diameter sizes and lengths.
