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.
Product features:
According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice avers. Usually we are offering 50mm, 63.5mm, 76mm, 89mm,102mm etc.
