4''-8'' QL Series High Air Pressure DTH Drill Hammer for Drilling Industry
Product Description:
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.
Product Advantages:
1.Wide range of holes sizes, including extremely larger hole diameter.
2.Excellent hole straightness within 1.5% deviation without guiding equipment, more accurate than top-hammer, due to the impact being in the hole.
3.Good hole cleaning, with plenty of air for the hole cleaning from the hammer.
4.Less amount of drilling fluid and additives are required.
5.Less weight-on-bit allows for lighter rigs that are easier to set up and takedown.
