Trade Lead Description:
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
water wells.
Suitable choice of raw material,
