Hexagonal drill rods are produced by CNC machining and advanced heat treatment .

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. Tapered drill rod is a further development of the integral drill rods. It usually has a forged collar to maintain the proper shank striking face position in the rock drill.
