The drilling efficiency of rock drills and the service life of pistons and air needles are closely related to the manufacturing quality of drill rods. Users are welcome to use standard drill rods produced by legitimate rock drilling machine manufacturers

A rock drill is a commonly used engineering machinery equipment, and the piston, as one of the core components of the rock drill, bears enormous axial and radial pressure. Therefore, the selection of its material is very important. The material of the piston not only directly affects the service life of the machine, but also affects the operational efficiency and stability of the machine.

A pin shaft is a mechanical connector composed of two parts. One of the parts is a pin, usually circular, and the other part is a shaft sleeve or hole sleeve, usually a circular hole. One end of the pin has a head, which is inserted into another part through the hole or passage of the shaft sleeve or hole sleeve.
