When choosing a ball end mill always chooses the largest size available.For the same stepover, a larger tool will leave smaller scallops, thus giving a smoother result.For a generally smooth model with some areas of fine detail, a large tool should be used for the overall job and a smaller tool should be used only to clean out detailed areas.
Ball end mills have a rounded nose and create a round-bottomed groove in milling tasks.Also known as ball-nose end mills, they are rotated against a workpiece to make round-bottomed slots and pockets or mill complex shapes without sharp corners.

When one end wears out, switch to the opposite end for two times the life of a standard cobalt steel end mill.With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as cast iron, hardened steel, titanium, and tool steel.
Ball nose end mills, featuring a full radius, are ideally suited for milling 3-d contoured parts.Corner radius corner radius end mills feature a radius at the corner edge of the mill.
In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature.As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.
A typical end mill may be referred to as an upcut spiral by the cnc router world.Other than small geometry changes to optimize for wood, end mills and upcut spirals are interchangeable.The more common spelling is end mill, but i often use endmill as well.The two are pretty interchangeable.Carbide vs hss end mills.

Ball end mills have a hemispherical tip used to machine rounded details, such as the metal bearing grooves found in machines.Also called ball nose end mills, they are used extensively in manufacturing tools dies, and machining complex three dimensional contours with a smooth finish.
End milling - an end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.
