Product Introduction
DTH hammer is a percussion drilling tool that is used to drill holes in rocks,soil and other hard materials.It is composed of a hammer bit,a piston and an air chamber. The piston moves back and forth within the chamber,causing the bit to strike the rock surface repeatedly at high speeds. The hammer bit has sharp,strong teech that help to break up the material as it is being drilled. This process is repeated until the desired depth is reached.
