Spiral Drill Rod
Product Detailed

The high-efficiency spiral drill rod can meet the practical needs for water and gas exploring and injection under the coal mine.

The high-efficiency spiral drill rod can meet the practical needs for water and gas exploring and injection under the coal mine. It adopts square coupling for rods connection, easy to assemble and disassemble. Its tension-resistance can be up to be 1323.89 MPa by using special steel material, smithing and heat treatment.
Matching our drilling machines with spiral dry drilling technology, it can keep high drilling speed and drilling efficiency. Compared with traditional drilling technology, it can avoid torsion and bend stress efficiently and improve the drilling speed.
In addition, it has large advantages in coal digging which adopting serried hole drill and gas discharging. And it can discharge gas and overcome the stress at high speed to achieve the out burst proof and ensure the coal digging safety.
We can manufacture as customer's requirements.
