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-available from 0.6 m to 3.6 m in length-are measured from the collar to the bit end. 
Shank Hexagon: 19 x108 mm, 22x 108mm, 25 x108 mm,  25 mmX159 mm  6, 7, 11, 12 degree taper in most lengths, taper degree of drill steel is mostly imports for excellent drilling productivity. 
For drilling medium-hard to hard and abrasive rock formations,Taper angles of 11 and 12-degrees are normally used on modern drill rigs, like our model no. PD-Y58 crawler hydraulic rock drill. Also for Y6, Y10, Y24, YT24, Mobile rock drill pneumatic and hydraulic. Types of drill rods     SpecificationsLength            (mm)ShankTapered drill rodsTaper Angle: 4, 6, 7, 11, 12 degree400mm to 8000mmHex22mm*108mm Hex25mm*159mm Hex19mm*108mmIntegral drill steelBit diameter: 26mm, 28mm, 30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 42mm400mm to 4800mmPlug hole rodsChisel bit diameter: 17mm, 20mm, 22mm150mm to 710mmMain Products:
