ZGYX series integrated open-air down-the-hole Dimension Surface Drill Rigs are widely used in stone factories for drilling operations.ZGYX series integrated DTH Surface Drill Rigs are highly flexible and suitable for various types of rock drilling operations. It is specifically designed for the demands of the stone factory industry due to its ability to drill holes of various depths and widths while maintaining precision and accuracy. This makes it ideal for drilling holes for the installation of anchors, fence posts, and other applications.

In the application of Dimension Surface Drill Rig, the air-leg rock drill can only drill small diameter, medium and shallow blast holes; The heavy guideway rock drill can also drill deep blastholes through the extension rod, but the energy consumption is large and the drilling speed is slow. The down-the-hole drill is characterized by that the energy loss when the piston strikes the drill rod does not increase with the extension of the drill hole. Therefore, it is suitable for drilling holes with large diameter and depth.
The down-the-hole drill is to use the impactor and the drill bit that penetrate into the hole bottom to impact and break the rock, so it is called the down-the-hole drill. Widely used in metal mines, hydropower, transportation.
