Top Hammer Drill Rods
Top hammer drill rod performs power transmission works in the drilling process, via which power from rock drill piston is transmitted to drill bits, and finally delivered into rocks. One side of the drill rod is connected to coupling or directly to the shank adapter, while the other side is connected with drill bit. Top hammer drill rods are suitable for drilling works for blasting duties in tunneling, construction, mining, quarrying, etc.
- Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;
- 23CrNi3Mo, which is in same league as Sandvik Sandbar 64, is applied as drill rod material.
- Cost-effective, good performance with reasonable price.
- Complete types of drill rod for various drilling scenarios.
Drilling duties in tunneling, construction, mining, quarrying, etc.
