What are the differences between milling cutter and drill bit?

Because the milling cutter contains one or more cutter teeth, it will be used in many machining processes, which greatly improves the efficiency of workpiece processing. Today's little sunflower nono class will give you popular knowledge. In addition to the characteristics of milling cutter, what are the differences between milling cutter and drill bit? Can a milling cutter be used as a drill? Let's have a look~
What are the characteristics of milling cutter?
1. Each tooth of the milling cutter periodically participates in intermittent cutting.
2. The cutting thickness of each cutter tooth changes in the cutting process.
3. Feed rate per tooth α F (mm / tooth), indicating the relative displacement of the workpiece within the time when the milling cutter rotates one tooth.
What are the differences between milling cutter and drill bit?
1. Different uses
Milling cutter is mainly used for machining plane, step, groove, forming surface and cutting workpiece on milling machine; Drill bit is one of the important tools for oil drilling, which is generally used for drilling.
2. Different categories
Milling cutter is generally divided into sharp tooth milling cutter and shovel tooth milling cutter; The bit is divided into diamond bit, cone bit and scraper bit.
3. Different rear angle
Milling cutter: the side edge of the milling cutter has a back angle, so it can cut laterally.
Bit: the side edge of the bit has no back angle, so it can not be cut laterally. It is used for axial drilling.
Can a milling cutter be used as a drill?
What if there is no drill in some special cases? If you have a single edge and a double edge or three edge milling cutter that passes through the center, you can also use it as a drill.
