High efficiency spiral drill rod Φ55

The drill pipe body is in a square or hexagonal shape and connected from head to tail. The spring pin automatically locks together and the U-shape retainer pin could bind together so you can quickly connect drill pipe. With the characteristics of quick connection, light weight, high flexibility, hard to bend, compared with other drill pipes, it has the advantages of easy operation, high speed drilling, and that's why it's called high efficient drill pipe. High efficiency drill pipe is widely used in drilling in the coal seam or similar geological conditions, for exploring the water and gas drainage borehole construction, and it can also be used for anchorage, drilling construction in the field of geophysical prospecting and construction of water conservancy projects. This kind of drill pipe can be divided into hole.
