Spiral craft: prestressed wire winding and welding with single strip steel or double strip steel, based on the big torque of geological drill rod.
Material of rod body: geological alloy pipe
Material of connector: first-class alloy constructional steel
Craft: thermal refining in vacuum, which greatly improves the fatigue resistance and shearing strength.
Rod body craft: friction welding, which improves the bending strength and the firmness of the drill rod.
 Production facility: CNC machining equipment, which guarantees the high production efficiency, steady quality and straightness.
Design feature: overlay spiral. It guarantees big torque, quick slagging, and clear hole forming. Besides, the drill bit will hardly get stuck.
Application: soft coal bed, and other formation similar to coal bed, which is hard to drain and deslag.
