7° 11° 12° Hexagonal Rock Drill Steel, Integral Drill Rod for Mining / Quarrying

Integral drill rods(integral rods or integral drill steels) are used for small hole drilling. Equipped with small power rock drills, like air leg rock drills, hand held rock drills, etc. integral drill steels can be used for drilling bore hole diameter from 29mm to 41mm usually. Integral drill rods are usually hexagonal with chisel tips or cross tips, the diameter are usually 19mm and 22mm.

Integral drill rods are ideal in small hole drilling, all integral drill rods consist of hex. rods with integrated cemented carbide chisel-shaped bit heads. With the same steels as and the best carbides made in China, we are supplying different lengths of integral drill rods with different head diameters.

According to different application, different lengths are available from 600mm to 9600mm usually. With the best hollow drill steels and tungsten carbides, sinodrills integral drill steels will show you very good performance.

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.

1. The Integral rods strong energy of single impact and the low energy consumption in rock crushing;

2. The weight ratio of Piston and Bit almost reached 1:1 to provide long effective acting time, which

leads to the improved efficiency in rock crushing and the extended service life of the drilling tool;

3. The Integral rods good performance in central air exhaust and cuttings discharge, which reduces

the repeated crushing of rock;

4. A check valve device is available to drill holes under water.

The HR Series DTH Hammer, an ideal drilling tool, is widely used in such industries relating to

energy,transportation, metallurgy, building etc.

In our after sales service system, We establish perfect control system strictly according to ISO-9000 series, in this system, technology date and problem solve solution and preventive measures will be provided in any maintain project, all the spare parts will be used in new OEM products with installation instructions, packing list, manufacturer's instruction, qualification and Warranty certificate.

We provide "one equipment & one case, endless service, namely the after sales service begin from the order confirmation, last for the working life of the equipment.
