SD6 High Air Pressure 6'' DTH Drill Bits with High Quality For Hard Rock Drilling
Product description
DTH hammer is a percussion system driving a piston inside hammer body with up and donw motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.
1. The most suitable hole diameter is 100–254 mm, in special applications can be up to 2M And the minimum can be around 50 mm as well.
2. Theoretically drilling depth is limited by back pressure only (can be up to several kilometers).
3. Adapt to hard rock and rock formation conditions (compared to top hammer).
4. Mainly use pressurized air for slag flushing, and sometimes air foam for special application.
5. Highly efficient in hard rock drilling (compared to the rotary drilling).
6. DTH drilling straightness is best in these three methods(rotary drilling, dth drilling and tophammer drilling)
