Advantage:
The entire hammer head is fully covered and the work efficiency is high at one time. The structure is simple and the stability is better. The single large hammerhead is basically unaffected to the rock formations with many cracks.
Disadvantages:
Limited by current production and processing equipment, material requirements, and pile hole quality, the large aperture is 1.2 meters. The air pressure is too high and the impact frequency is low. The single DTH hammer has more than 100,000 hammer heads, and the manufacturing cost is high.
