Geological spiral drill rod is made based on geological drill rod with large torque performance, through one more time process spiral blade on it, through prestressed wire winding process, fully automatic welding process to become. It has drilling long, high efficent discharge performance. The body of drill rod is made of high grade geological special alloy steel tube, the joint of drill rod is made of high grade Alloy Structure Steel. Through High Pressure Forming process, Vacuum hardening the tempering processing, friction welding process seiko produced. It has high bending strength, firmly welding, high efficiency discharge, etc characteristics. Greatly improve the Fatigue Strength and Shearing Strength.

 

High blade spiral flight applies to long hole drilling of above medium hard formation, low blade spiral applies to soft geological condition, soft coal seam and gas exhausting, it has features of high efficiency discharge, high rate to drill hole,no frequent getting stuck.

 

The type of Spiral flight welding, there are single flight, double flight, three ends or multi ends etc,(customize as request of customer).
