(Middle row in image) Are generally HSS cutting tools with three or more flutes. They are intended for bulk metal removal with their flutes and unless they are ground with cutting edges that cross the axis (as those in the image show) then they are only suitable for side cutting.

Side and face cutter

The side and face cutter is designed with cutting teeth on its side as well as its circumference. They are made in varying diameters and widths depending on the application. The teeth on the side allow the cutter to make unbalanced cuts (cutting on one side only) without deflecting the cutter as would happen with a slitting saw or slot cutter (no side teeth)

These tips may be rotated within the holder to present a fresh face to the workpiece, this increases the life of the tip and thus their economical cutting life. The tips are not designed to be resharpened and are selected from a range of types that may be determined by various criteria, some of which may be: tip shape, cutting action required, material being cut.

Metalworking - Wikipedia, the free encyclopedia (1058 words)
Milling is generally done on a milling machine, which is a power-driven machine used for the complex shaping of metal (or possibly other materials) parts, by removing unneeded material to form the final shape.
Its basic form is that of a milling cutter that rotates about the spindle axis (like a drill), and a worktable that can move in multiple directions (usually three dimensions [x,y,z axis] relative to the workpiece, whereas a drill can only move in one dimension [z axis] while cutting).
Milling machines may be operated manually or under computer numerical control (CNC), and can perform a vast number of complex operations, such as slot cutting, planing, drilling and threading, rebating, routing, etc. Two common types of millers are the horizontal miller and vertical miller.
