Tapered drill rods effective lengths are measured from the collar to the bit end, which are usually from 0.6meter to 3.6 meters.
Our tapered drill rod adopts an integral carburizing process, it increases the carbon content of the surface of the drill rod, thereby improving the surface hardness and overall strength, and enhances the service life of the taper drill. The wear resistance is also better. Under the same mining industry, the life of the overall carburizing taper drill is several times that of the ordinary taper drill.
