DTH drill pipe, also known as down-the-hole drill pipe, is a kind of rock drilling drilling tool used in the matching of down-the-hole drilling rig. The down-the-hole drill rod, the down-the-hole impactor and the down-the-hole drill bit together form a down-the-hole drilling tool. The working principle of the down-the-hole drilling tool is to use compressed air as the power to submersible the impact power part of the rock drilling tool into the rock drilling hole. The gas distribution device controls the piston to make a reciprocating motion to impact the down-hole drill bit. The drill bit breaks the rock.
Drill tail (English shank adapters) is also known as hydraulic drill drill drill tail, pneumatic drill drill drill tail. The drill tail is an important part of the rock drill and an important part of the drill set. During the rock drilling operation, the rock drill transmits the impact work and rotating torque of the rock drill to the drilling tool group through the drill tail, and the rock drilling operation is completed by crushing the rock through the drill head.
