Integral drill rod is a kind of drilling tool with the tapered drill bits, tapered drill rods and shank merged together.
The drilling tools are designed to transmit the maximum impact energy to the rock with the least possible loss of energy in the drilling chain.
Integral drill rod has the advantages of eliminating the energy loss at the junctions of the taper drilling tools, resulting in a higher efficiency and avoiding the lose of taper drilling bits.. All the advantages make this drilling steels not only apply to the excavate project, but also the outdoor-drilling downwards, furthermore, integral drill rod extends its application range from that of the taper drill rods to the scope of secondary rock breaking of pick rods.
Chemshine provides a variety of integral drill rods in a full range of lengths and bit diameters for all of your hand-held pneumatic drilling needs.
In order to improve the efficiency, the head of integral drill steel can be grinded into a taper rods after the normal retirement of the tungsten carbide.
