The down the hole drilling rig is an efficient medium deep hole rock drilling equipment, whose core feature is to directly install the impactor (down the hole hammer) behind the drill bit and send it to the bottom of the borehole for operation. This design allows the impact energy to directly act on the rock, reducing energy transfer losses and significantly improving drilling speed, drilling accuracy, and depth capability in hard rock formations.
