[0002] A drilling machine is a machine or device that uses a tool that is harder and sharper than the target object to leave cylindrical holes or holes on the target object through rotary cutting or rotary extrusion. There are two types of drilling machines: semi-automatic drilling machines and fully automatic drilling machines. The working principle of the drilling machine is that the drive motor provides power, which is transmitted to the drill bit through belts and gears, causing the drill bit to rotate and drill holes in the ground or material.
