The earliest drilling machines were mechanically driven, with a relatively simple structure and poor performance. In the early 1950s, they developed into a combination of mechanical and hydraulic systems, with an increase in variable speed levels and some parameters being controlled by instruments. Since the 1970s, in order to adapt to high-speed diamond drilling, the degree of hydraulics has increased, and the rotation speed of drilling tools can reach up to 1000-1500 revolutions per minute, some as high as 2400 revolutions per minute, greatly improving drilling efficiency.
