The difference between a tapping machine and a drilling machine
The main difference between a tapping machine and a drilling machine is that they differ in their functions and uses Tapping machines are mainly used for machining internal threads, while drilling machines are mainly used for making holes in workpieces.

The drilling machine uses a drill bit for processing, the drill bit rotation is the main movement, and the axial movement of the drill bit is the feed movement. When drilling, the motor rotates forward, and when retracting, the motor still rotates forward, and the drilling rate is higher . The tapping machine uses a tap for processing, the tap rotation is the main movement, the speed is low, and the motor is reversed when the tool is withdrawn.

The application scenarios of tapping machines and drilling machines are also different. The drilling machine is suitable for various situations where a hole needs to be punched in the workpiece, whereas the tapping machine is specially designed to make thread 3 in the inner hole. Tapping machines are often more flexible and efficient than drilling machines, avoiding the limitations of lathes, drilling machines, or manual tapping.

There are also significant differences in the structure and function of tapping machines and drilling machines. Drilling machines are usually simple in structure and are mainly used for drilling operations, while tapping machines are designed to machine internal threads precisely with high precision and efficiency . The relatively slow speed of the tapping machine ensures a smooth thread surface and high quality.
