Down-the-hole rock tools (drilling tools) are rock drilling
equipment which takes compressed air as power source to partially
transfer impact power into drilling holes. An air distributing
device in a top hammer controls a piston to move back and forth. An
impact device arranged in the front of the top hammer transfers the
impact powder to a down-the-hole bit to crush rocks.
• Our product range covers the most diverse applications in mining,
natural resources exploration, water wells, quarries and civil
• Our products go from 3 to 25 inches drilling diameter.
• Sollroc enhances its product line with a number of accessories
and peripheral products, seeking to add value to the end user of
Down The Hole equipments.
Down The Hole (DTH) Hammer
When percussion or hammer drilling the percussion mechanism is
called a DTH or down the hole hammer. This drilling tool is located
directly above the down hole hammer bit. The driller transfers
weight to the bit through the drill pipe as well as provides some
rotation. Through the use of a compressor, the pressurized air is
forced to the down hole hammer. As the drilled hole gets deeper the
driller adds more drill pipe to the string. The piston strikes the
impact zone of the hammer bit; hammers are always used as part of a
casing advancement system and can be used in reverse circulation
applications. DTH hammers are common when drilling blast holes and
Suitable choice of raw material, advanced processing technology and
perfect quality warranty.
With hardened treatment, drilling life can be extended and then
cost can be reduced.
