Tapered Drill Steel also called taper steel, Hand held steel or short hole steel. It provides a hexagonal chuck section to provide leverage for the rotation chuck bushing. It usually has a forged collar to maintain the proper shank striking face position in the rock drill, and a tapered bit end. Tapered steel lengths are measured from the collar to the bit end. 

There are two standard steel hex diameters - 22mm or 25mm. And Our tapered bit and rods come in a variety of taper angles(6 degree, 7 degree, 11 degree, 12 degree)

GMD tapered rods are available with high-frequency or fully carburized heat treatments. 

Different Taper angles are used in different machine. Such as 11 and 12 degrees are normally used on heavy-duty modern hydraulic drill rigs. While, 6 and 7degree rods will be applied for light-duty rock drill ,such as the pneumatic rock drill Y6, Y10, Y24, YT24,Y26,Y19A,YT27,YT29,YT28 and the line drilling rigs.
