Product Description

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 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 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.

Low air pressure hole Diameter: 65-220mm
