CNC End Mill Comparison Guide | MatterHackers
Ball-Nose End Mills. Ball-nose end mills have a dome-shaped tip. These excel at high-detail contours like relief artwork or mold and die making, but have what is known as "scalloping." Since the tip of the end mill is round, having a perfectly flat surface is a challenging feat and will take many more passes than a simple fishtail to smooth ...
