What's the difference between a cutter and a drill bit?
The main difference between the milling cutter and the drill bit is that the side edge of the milling cutter has a rear angle so that it can be laterally cut. The side edge of the drill has no back angle, so it can not be cut laterally and used for axial drilling
Popular point of the milling cutter is the processing plane, with the blade of the ground is flat, so you can not directly like a brick vertical feed, and the drill has a 120 reading angle can be vertical feed, but not parallel washing

The margin of each in turn cutter tooth intermittently cut work. The milling cutter is mainly used to process the plane, the step, the groove, the forming surface and the cutting workpiece and so on in the milling machine. In order to ensure a sufficiently high average chip thickness / feed per tooth, the number of cutter teeth suitable for the process must be correctly determined.
