Roschen offers the largest assortment of conventional down-the-hole
(DTH) hammers in the whole industry. Their hammers outdistance the
competitors’ hammers in both speed and longevity. The large amount
of Roschen hammers and 4 hammer models allow you to drill holes
varying between 89mm - 1219mm in diameter. The hammers drill at a
high frequency to provide less vibration and ensure a smooth
operation. They are also able to drill efficiently against high
heads of water.

What is Low air pressure DTH hammer ?
Low air pressure DTH hammer is widely used in geotechnical
engineering in a variety of hard, high hardness and other toughness
can be poor tough rock, the following characteristics:
1. Low air pressure DTH hammer is a valve-type center exhaust
hammer, the discharge of rock powder effect is good, reducing the
re-broken rock slag, reducing the wear of the drill, improve the
drilling efficiency.
2. Using the latest rock design theory to design the hammer of the
internal structure of the size of the hammer to obtain the ideal
energy transfer, a single hammer power, drilling faster, lower air
consumption.
3. Selection of the highest quality raw materials and the most
advanced processing technology, more stable performance, longer
life.
4. Easy disassembly, low failure, easy maintenance.
The application of Low air pressure DTH Hammer:
Mining, quarrying, road construction and other projects drilling
blasting hole, landslide protection, dam reinforcement, anchoring
and other engineering holes, geothermal air conditioning,
hydrology, wells and other fields.
