Stubby, ball end mills are typically used to take light cuts at fast feed rates in titanium and stainless parts. Minimizing tool gage length helps maximize stiffness. According to Mr. Snow, light cuts are also less likely to introduce stress into the material, so parts with thin walls won't "pop" out of shape after machining.
