High Air Pressure Down The Hole Hammer with Shank QL60 for Africa Mining
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.Reduces auxiliary time effectively.
2.Reduced risk of getting stuck in fractured and faulted rock conditions.
3.Good hole cleaning, with plenty of air for the hole cleaning from the hammer.
4.Lower cost on drill rod consumables, due to drill string is not subjected to heavy percussive force as with top hammer drilling and drill string life is therefore greatly lengthened.
5.Efficient energy transmission and deep hole drilling capacity, with constant penetration and no energy losses in joints through the drill string from start to finish of the hole, as with top hammer.
