End Mills. Endmills generally come in 2 varieties: Square End Mills and Ballnose end mills. Aside from the shape of the endmill, the tip geometry also varies between types, determining the way the chips are ejected and effecting the smoothness of the finish. Up-Cut. Up-cut end mills 'pull' the chips UP and out of …
Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.
End mills come in a variety of grades. To find your best end mill value I have found it is best to match the end mill to the work. Most of my machine work is in aluminum so I get by with cheaper end mills. I almost always buy them coated. The Hertel and Interstate brands are not bad. The no name brands called "Imports" are the lowest grades.
Iscar Metals (Arlington, TX] has launched a new family of face mills and end mills-called the FEEDMILL family--that employ trigon-like shaped inserts with a large-radius cutting edge configuration. This setup means that cutting forces are directed axially toward the spindle so that there is both high stability and the ability to machine at high ...
Bull end mills are simply corner radius end mill cutters. These radius end mills are single ended tools used for making corner radii at the bottom of a milled shoulder. Corner radius end mill cutters have a stronger milling edge than square end mills, so feed rates may be increased and yield longer tool life and greater productivity.
The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
