Ball nose end mills (also called ball end) create contoured surfaces, where sharp corners are not required.
Chamfer (also called drill-point) end mills narrow to a point at the end to create beveled and angled cuts. When the point is sharp, it can also be used for drilling and countersinking.
Corner rounding end mills have a concave, curved indent on the cutting end to create a more rounded or less rounded external corner, depending on the radius selected.
Radiused corner end mills have a square end with rounded corners on the cutting edges to reduce chipping and extend the life of the tool.
Square nose end mills have a square angle at the end, and create sharp, unrounded cuts in a workpiece.
Tapered end mills have flutes that narrow from the shank to the tip. They are suitable for producing the draft or clearance angles in die and mold walls to facilitate ejection of the part after molding. Larger degrees of taper create larger angles, making ejection easier.
