FC Series DTH Hammer

The FC series DTH hammer is driven by compressed air to operate the down-the-hole hammer located at the bottom of the hole, breaking rock volumetrically by impact. The broken cuttings are rapidly discharged with mud through the central pipe in a reverse circulation manner, greatly reducing repeated breakage. Therefore, this DTH hammer percussive-rotary drilling method features fast hole formation, high drilling efficiency, and good hole quality, and is especially advantageous in rock formations of medium hardness and above, with construction efficiency higher than conventional drilling methods.

Suitable for construction in hard rock formations, gravel-cobble layers, and boulder layers.
