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.

Features 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. Applications

Drilling duties in tunneling, construction, mining, quarrying, etc.

Integral Drill Rod

Connected to rock drill, the integral drill rod can be directly deployed for drilling.

Parameters Rock drill connection: H22*108mm Diameter: 26mm-41mm Length: 800mm-8000mm Taper Drill Rod

With one side connected to rock drill and the other side connected with taper drill bit, the taper drill rod transmits power from rock drill to bit, drilling work is thus performed.

Parameters Rock drill connection: H22*108mm Conical degree: 4°46’ , 6°, 7°, 11°, 12° Length: 400mm-8000mm

MF Drill Rod

Extension Drill Rod

Extension drill rod transmits power from rock drill piston to rock, one side of the rod is connected to coupling or shank adapter, while the other side is connected with threaded drill rod.

Parameters Thread type: R25, R28, R32, R38, T38, T45, T51 Diameter: Hex.22, Hex.25, Hex.28, Hex.32, Hex.35.
