The quick-connect spiral drill rod is connected end to end with a square or hexagonal shape, and uses a spring pin to automatically lock or a semicircular pin, a straight pin, a U-shaped pin, or an oblong wedge pin for connection and positioning. It can be quickly connected. The connection is convenient and fast, and it has the characteristics of light weight, high elasticity, and not easy to bend. Compared with other drill rods, it has the obvious advantages of easy operation and fast drilling speed, so it is also called a high-efficiency spiral drill rod.

Long spiral drill rods have the characteristics of fast drilling speed, good hole formation, high drilling efficiency, greater torque, stable operation, automatic locking of spring pins, and convenient and rapid disassembly.
When drilling deep holes, the long spiral drill rod is also equipped with a cotter pin to increase the transmission torque and greatly reduce the loss of the drill rod. It adopts an inserted threaded connection, which is easy and swift to disassemble and assemble, and has good sealing performance, high tensile strength, and high pile quality. It has good verticality and is easy to disassemble and install.
The models of long spiral drill rods are available in diameters of 400mm, 500mm, 600mm, 700mm, and 800mm.
Auger spiral drill rods are widely used in drilling operations under geological conditions of coal seams and near-coal seams, as well as in the construction of water exploration and gas drainage boreholes in coal mines. It can also be applied to anchoring and drilling construction projects in geophysical exploration and water conservancy construction engineering.
