API 2 3/8" REG And API 3 1/2" DTH Drill Pipe REG Friction Welded
DTH Drill Rod
Product description
DTH drilling tool is a kind of drilling system which uses
compressed air as motivation, makes drilling impact motivation
parts down the hole, to control the piston reciprocating motion by
the distribution device in the hammer, and then impacts the DTH bit
in the front of the hammer to transit the impacting power to the
bit. The DTH bit in the front of the hammer breaks the rock to
drill hole.

Advantages and applications
At present, DTH drilling tool is widely used in underground mining,
quarries, hydraulic and Hydro-Power Engineering, water well
drilling, Mineral exploration, anchoring hole drilling, geothermal
engineering, Subway excavation, another civil engineering. It has
the advantage of high flatness, smooth hole wall, high rigid of
drill rod and hammer, independent of high axial thrust, no limit of
drilling depth, low cost of devices and easiness to maintain. At
the drilling hole of dia.105mm-dia.254mm, a plenty of the DTH
drilling tools are used.
