Square end mills cut a flat bottomed groove with 90 inside corners. Roughing end mills also known as hog mills are used to quickly remove large amounts of material during heavier operations.

Machining a groove or slot often called full slotting involves three machined faces. Each end mill has flutes on its cutting head that carry the removed material away from the workpiece to prevent damage to the end mill or workpiece. Corner chamfer and corner radius end mills make a flat bottomed. Ball end mills create a round bottomed groove in a workpiece.

The axial cutting depth should be generally reduced to around 70 of the edge length. Rounded edge square end mills often used for slotting and pocketing cuts in mold and die making these end mills have a 90 profile with rounded corners which reduce flute breakage and chipping. Ball end mills also known as ball nose end mills are used for milling contoured surfaces slotting and pocketing.
