DHD360 DTH Drill Hammer with Specical Steel and Black for Quarrying
Services
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. Mainly use pressurized air for slag flushing, and sometimes air
foam for special application.
2. Highly efficient in hard rock drilling (compared to the rotary
drilling).
3. DTH drilling straightness is best in these three methods(rotary
drilling, dth drilling and tophammer drilling)
4. Safer drilling in sensitive formations.
5. cost-efficient and environmentally friendly drilling.
