Threaded connection bit (also known as threaded connection bit) is a kind of rock drilling tool, mainly used to drill holes in the rock. In the process of rock drilling, the drilling tool group composed of drill bit, drill rod, connecting sleeve and drill tail transmits the impact work of the rock drill, and the drill bit directly drills the rock.

DTH drill bit (also called DTH drill bit) is a kind of rock drilling tool used in supporting DTH drilling rig. The down-the-hole drill bit, the down-the-hole impactor and the down-the-hole drill pipe together form the down-the-hole drill tool. The working principle of the down-the-hole drill tool is to use compressed air as the power to submerse the rock drilling impact power part into the rock drilling hole, and the air distribution device in the impactor controls the piston to make a reciprocating motion to impact the down-hole drill bit and the drill bit breaks the rock. DTH drilling tools are mainly used in open-pit mining, geothermal drilling of water wells, quarries, excavation of building foundations, anchoring operations of water conservancy and hydropower projects, etc. Compared with other rock drilling machinery and equipment, the DTH drilling tool has a deep drilling depth, a large drilling hole size, a high drilling straightness, a low investment in the DTH drilling machine, and a wide range of applications.
Key words:
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.
Key words:
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.
