Product description
In DTH drilling, the drill string rotates while the drilling hammer
continuously strikes down into the rock. Inside the hammer, a
piston powered by compressed air gives the drill bit its striking
power. This combined with the rotational movement means the rock is
crushed in a very efficient manner. 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.

Product featutres
1. Simple design of the piston. Long life. Valveless air distribution. More reliable.
2. More efficient energy transfer, fact drilling speed, lower air
consumption and lower oil consumption.
3. Fewer internal parts, simple structure, long life, less failure
and easier to maintain because all the parts are heat treated.
4. Easy to disassemble because the top sub, the drive chuck and the
external cylinder are connected by multi-step thread.
Advantages and application
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.
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.
