Product description
High Pressure DTH Air Drill DHD3.5 is very popular in international mining drilling and rock excavation field.
Product introduction:
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

Product features
1. DTH hammer with backward-impact-damping design.
2. Capable to withstand solids content in drilling fluids.
3. Valveless air distribution. More reliable.
4. Simple design of the piston. Long life.
Application
DTH drilling tool is a kind of drilling system which uses compressed air as motivation, makes drilling impact motivation parts down the hole, to control the piston reciprocating motion by the distribution device in the hammer, and then impacts the DTH bit in the front of the hammer to transit the impacting power to the bit. The DTH bit in the front of the hammer breaks the rock to drill hole.
