     · Finally a ball profile features flutes with no flat bottom and is rounded off at the end creating a "ball nose" at the tip of the tool. This is the strongest end mill style. A fully rounded cutting edge has no corner removing the mostly likely failure point from the tool contrary to a sharp edge on a square profile end mill.
