DTH Drill Rod

DTH drill rod

DTH drill pipe is a new type of DTH drill pipe, which is composed of rod barrel, male joint and female joint. The rod barrel, male joint and female joint are provided with axial holes, and the rear end of male joint and the front end of female joint are embedded into the axial hole of the rod barrel by both ends of the rod barrel in interference fit mode.A shaft shoulder is arranged on the male joint and female joint of the DTH drill pipe, and the end face of the rod barrel is welded to the end face of the shaft shoulder of the male joint and the female joint.The DTH drill pipe is a new type of drill pipe and the male and female joints are connected by radial interference fit and welded from the axial end face, so the DTH drill pipe has a high torsional strength, which can meet the drilling needs.It has the characteristics of less equipment investment and light weight of drill pipe.

Usage:

42mm, 50mm, 60mm dth drill pipe is mainly used on our XDQ70 and XDQ100 portable dth drilling rig for 50mm -130mm diameter,5-30m depth slope protection project hard rock drilling, or open-pit mine blasting hole hard rock drilling. They also used on soil drilling which weld auger vane on the pipe outside with three-wings bit drilling .

Applications of DTH Drill Rod / DTH Drill Pipe

The DTH drill rod is widely used in various drilling scenarios where efficiency, precision, and durability are critical. Its design allows it to perform consistently in both surface and subsurface rock conditions.

1. Slope Protection and Foundation Engineering

DTH drill pipes are commonly used in slope stabilization and foundation reinforcement projects. They are suitable for drilling anchor holes in hard rock formations with diameters ranging from 50mm to 130mm, ensuring strong structural support in civil engineering projects.

2. Open-Pit Mining Operations

In mining environments, the DTH drill pipe is used for blast hole drilling in hard rock formations. It provides excellent penetration speed and maintains stability even under high-impact drilling loads, making it ideal for large-scale mining production.

3. Water Well Drilling

The drill rod is widely applied in water well construction, especially in medium to deep boreholes. Its friction-welded structure and heat-treated body ensure reliable performance in long-duration drilling tasks.

4. Soil and Mixed Formation Drilling

For softer ground or mixed geological layers, the drill pipe can be adapted with external auger vanes and tri-wing bits, enabling efficient soil drilling and improved cuttings removal.

5. Portable and Small Rig Applications

The 42mm, 50mm, and 60mm configurations are particularly suitable for compact drilling systems such as portable rigs. These sizes are commonly matched with XDQ70 and XDQ100 drilling rigs, offering flexibility for field operations with limited space or mobility requirements.
