Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.

Also known as taper degree end mills, these end mills are angled from anywhere between 1/2° and 45° for machining angled slots in dies and molds. Ball End Mills Good for rounded slots, sloping cuts, and contours, ball end mills have a rounded cutting edge.

IMHO, the best way to do that is to conventionally mill 0.010-0.011 off each side, and then climb mill the remaining couple/few thou.
