Advantages of TDD Low air pressure DTH hammers:

low pressure DTH hammer belongs to the valve-type central exhaust hammer, which has good effect of discharging rock powder, reduces repeated crushing of rock debris, reduces the wear of the drill bit, and improves the drilling efficiency;  Using the latest rock drilling theory to design the internal structural dimensions of DTH hammer, DTH hammer will achieve the desired energy transfer, with a single impact power, faster rock drilling and lower air consumption;  Using the best quality raw materials and the most advanced processing technology, the performance is more stable and the life is longer.  Easy to disassemble, low failure and easy maintenance.

Scope of application: Mining, quarrying, road construction and other engineering drilling blastholes, landslide protection, dam site reinforcement, anchoring and other engineering holes, geothermal source air conditioning, hydrology, water wells and other fields.
