Description
High air pressure 5 INCH DTH hammer
A high air pressure DTH (Down-The-Hole) hammer is a specialized drilling tool used in mining, construction, and geotechnical engineering applications. It is designed to create boreholes or drill blast holes in hard rock formations.
It operates by using compressed air to drive a piston that strikes the back of a drill bit, causing it to penetrate the rock. The high-pressure air is supplied from an air compressor and is delivered through the drill pipe to the hammer.
Parameters
5 Inch Down-the-hole hammer:
A high air pressure DTH (Down-The-Hole) hammer is a specialized drilling tool used in mining, construction, and geotechnical engineering applications. It is designed to create boreholes or drill blast holes in hard rock formations.
The DTH hammer operates by using compressed air to drive a piston that strikes the back of a drill bit, causing it to penetrate the rock. The high-pressure air is supplied from an air compressor and is delivered through the drill pipe to the hammer. The air pressure can range from several hundred to several thousand pounds per square inch (psi), depending on the specific application and requirements.
We have the 5 inch DTH hammer of different bit shank including DHD350/SD5/QL50/M5 to borehole from 135mm-155mm with high drilling efficiency.
