The FC series down the hole hammer uses compressed air to drive the down the hole hammer located at the bottom of the hole, and crushes the rock volume by impact. The crushed rock fragments are quickly discharged from the mud through the central pipeline in a reverse circulation manner, greatly reducing the phenomenon of repeated crushing. So this down the hole hammer impact rotary drilling method has the advantages of fast drilling speed, high drilling efficiency, and good drilling quality, especially in medium and above rock layers, with higher construction efficiency than conventional drilling methods.
Suitable for construction in hard rock formations, gravel layers, and isolated stone layers.
