Product Description

Advantages

1. The drill rod body is made of high quality geological special alloy steel pipe, and the drill rod joint is made of high quality alloy structural steel. After vacuum quenching and tempering treatment, the fatigue strength and shear strength are largely improved.
2. Adopting advanced friction welding technology, the drill pipe has the characteristics of high bending strength and strong welding.
3. The production equipment completely adopts advanced CNC processing equipment, high production efficiency, high quality and stability.
4. It can guarantee the straightness requirements in deep hole drilling. This product has high fatigue strength and long service life.
5. According to the actual needs of users, we can design and produce various special specifications and performance drilling tools.
