What is the difference between milling cutter and drill?

The main difference between a milling cutter and a drill bit is: the side edge of the milling cutter is ground with a clearance angle, so it can be cut sideways. The side edge of the drill bit has no clearance angle, so it cannot be laterally cut for axial drilling.

Milling cutter: is a rotary tool with one or more teeth for milling. When working, each cutter tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting workpieces on milling machines. To ensure that a sufficiently high average chip thickness/feed per tooth is used, it is necessary to correctly determine the number of teeth of the milling cutter suitable for the operation.

Generally divided into:

1. Flat-end milling cutter for rough milling, removing a large amount of blanks, fine milling of small horizontal planes or contours.

2. Ball end milling cutter for semi-finishing and finish milling of curved surfaces; small ball end milling cutter can finish milling steep surfaces/small chamfers of straight walls and irregular contour surfaces.

3. The flat end milling cutter has chamfering, which can be used for rough milling to remove a large amount of blanks, and can also finely mill small chamfers on fine flat surfaces (relative to steep surfaces).

4. Forming milling cutters, including chamfering cutters, T-shaped milling cutters or drum cutters, tooth cutters, and inner R cutters.

5. Chamfering cutter, the shape of the chamfering cutter is the same as that of the chamfering, and it is divided into milling cutters for rounding and chamfering.

6. T-shaped knife can mill T-shaped grooves.

7. Tooth cutter, milling out various tooth shapes, such as gears.

8. Rough skin cutter, a rough milling cutter designed for cutting aluminum and copper alloys, which can be processed quickly.
