Integral drill rod

Integral Drill rod, another name called Integral Drill Steels, integral rods are used by Hand Held Rock Drill in granite and marble quarries, underground mining, for small blasting hole drilling shank H22x108mm, H19x108mm, and standard hex. Bit diameters include 20-42mm, different lengths are available from 400mm to 6000mm usually.

It can reduces the expense of impact energy, improves the drilling speed and efficiency, also it can be used for drilling bore hole diameter from 30mm to 41mm usually. Each rods use premium quality alloy steel and excellent quality tungsten carbide to assure.

Tapered drill rod,another name called taper rod, tapered drill steels, This 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—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.
