Product Description
DTH Hammers:
The DTH Hammer is the working installation of the DTH Drill, dividing into low, medium and high air pressure series.
Be widely used to pore-forming operations on Metallurgy, Coal, Chemical, Mine, Water conservancy, Hydropower, Highway, Railway, Defense and Building projects, suitable for dry-type and wet-type operation, an ideal hole-drilling equipment with reliable capability.
Outstanding advantages:
1. Deep hole drilling capacity
2. Reliable performance
3. Easy to disassembly.
Super Drill Series High air pressure DTH Hammers:
The Super Drill Series High air pressure DTH Hammers is new developed, with better flushing off effect, not easy to block slag; with higher efficiency and more energy saving (drilling speed 15-30% higher, 20-30% energy saving).
Model: ND380,ND480, ND580, ND680, ND880, ND980,ND1080
We can also manufacture the DTH Hammers according to the customers' detailed requirements.
