High-speed steel ball end mills offer good wear resistance for general purpose milling applications. They're more flexible and can absorb more shock and vibration than carbide, powdered-metal, or cobalt steel end mills. Also known as ball-nose end mills, ball end mills have a rounded nose and create a round-bottomed groove in milling tasks.
