6''-8'' High Air Pressure DTH Hammer with Foot Valve Type for Foundation Work

Product description:
Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock

Product Advantages:
1.The most suitable hole diameter is 100–254 mm, in special applications can be up to 2M And the minimum can be around 50 mm as well.
2.Theoretically drilling depth is limited by back pressure only (can be up to several kilometers).
3.Adapt to hard rock and rock formation conditions (compared to top hammer).
4.Mainly use pressurized air for slag flushing, and sometimes air foam for special application.
