Description
High air pressure 4 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.
